 Something to consider when having more than a single user on the system is the security situation. The original administrator user will have access to all of the data for other users (including their encryption keys), so if you do add extra users they need to have *complete trust* in the administrator.

77 78
 Another point is that Freedombone installations are not intended to support many users (maybe ten at most). Large numbers of users may make the system unstable, and the more users you have on one system the more it becomes a single point of failure and also perhaps a honeypot from the standpoint of adversaries. Think of what happened with Lavabit and the moral dilemma which an administrator can be faced with (comply with threats and betray the trust of your users or don't comply and suffer other consequences). Ideally, you never want to put yourself into a situation where you can be forced to betray others.

 On mobile there are various options. The apps which are likely to be most secure are ones which have end-to-end encryption enabled by default and which can also be onion routed via Orbot. End-to-end encryption secures the content of the message and onion routing obscures the metadata, making it hard for a passive adversary to know who is communicating with who.

 Yes. The minimum requirements are to have some hardware that you can install Debian onto and also that you have administrator access to your internet router so that you can forward ports to the system which has Freedombone installed.

 The FreedomBox project supports Raspberry Pi builds, and the image build system for Freedombone is based on the same system. However, although the Raspberry Pi can run a version of Debian it requires a closed proprietary blob in order to boot the hardware. Who knows what that blob might contain or what exploits it could facilitate. From an adversarial point of view if you were trying to deliver "bulk equipment interference" then it doesn't get any better than piggybacking on something which has control of the boot process, and hence all subsequently run processes.

 Github is paradoxically a centralized, closed and proprietary system which happens to mostly host free and open source projects. Up until now it has been relatively benign, but at some point in the name of "growth" it will likely start becoming more evil, or just become like SourceForge - which was also once much loved by FOSS developers, but turned into a den of malvertizing.

 It was originally designed to run on the Beaglebone Black, but that should be regarded as the most minimal system, because it's single core and has by today's standards a small amount of memory. Obviously the more powerful the hardware is the faster things like web pages (blog, social networking, etc) will be served but the more electricity such a system will require if you're running it 24/7. A good compromise between performance and energy consumption is something like an old netbook. The battery of an old netbook or laptop even gives you <a href="https://en.wikipedia.org/wiki/Uninterruptible_power_supply">UPS capability</a> to keep the system going during brief power outages or cable re-arrangements, and that means using full disk encryption on the server also becomes more practical.

 Yes. Freedombone can support a small number of users, for a "<i>friends and family</i>" type of home installation. This gives them access to an email account, XMPP, SIP phone and the blog (depending on whether the variant which you installed includes those).

 Almost everywhere on the web you will read that self-signed certificates are worthless. They bring up <i>scary-scary looking</i> browser warnings and gurus will advise you not to use them. Self-signed certificates are quite useful though. What the scary warnings mean - and it would be good if they explained this more clearly - is that you have an encrypted connection established but there is <i>no certainty about who that connection is with</i>.

 Welcome to the world of email. Email is really the archetypal decentralized service, developed during the early days of the internet. In principle anyone can run an email server, and that's exactly what you're doing with Freedombone. Email is very useful, but it has a big problem, and that's that the protocols are totally insecure. That made it easy for spammers to do their thing, and in response highly elaborate spam filtering and blocking systems were developed. Chances are that your emails are being blocked in this way. Sometimes the blocking is so indisciminate that entire countries are excluded. What can you do about it? Unless you control the block list at the receiving end you may not be able to do much unless you can find an email proxy server which is trusted by the receiving server.
