First, I'll stick a few questions here that I thought up of off the top of my head:
Q: What is this forum all about?
A: Basically, one seemingly random day, the anonymous developers of Truecrypt decided to quit (why, we don't really know, but half of us thinks they wanted to stop and the other half thinks they were forced to stop), causing quite a commotion among security-minded people and truecrypt users. Some of these people decided to form a site to collect together an effort to continue truecrypt development. Since this effort has been merged with ciphershed, this site now forms a section of the pure privacy association's website.
Q: Why would I need this? I've got nothing to hide.
A: Say that again when those sex tapes you took with a former girlfriend, your credit card number (with security digits), you address, and that embarrasing video remix you made for yourself are found and you're now dealing with random people coming to your front door to harass you. We all have something to hide, and it's nobody's business except yours what you give. It isn't just criminals and internet trolls that like privacy.
Q: Ok, I have my private data encrypted. Is it safe now?
A: No, not yet. First, NEVER give it out to anyone/anything you don't absolutely trust, and double-check the URL of websites before you enter your passwords in. Second, set up antivirus, antimalware, and a firewall (I personally like Bitdefender, Malwarebytes, and Zonealarm) if you run windows or os x (linux gets a pass because the design of most distros makes it so unintentionally installing malware is hard), and make sure you keep your software well-updated (applies to windows, os x, and linux). Third, keep an eye on your computer at all times, and follow common-sense security practices such as not clicking random attachments in email and not using common passwords. Fourth, get a handle on other open-source privacy tools such as tor and GPG. Fifth, lay low, and don't look like a good target. Sixth, for the really paranoid, access your data only on a live OS such as tails. I can't guarantee anything, but if you can keep all this in mind at all times, you should be better off.
Q: Is truecrypt safe to use?
A: Yes, probably. A first pass by a truecrypt audit didn't find major bugs, and even the NSA has trouble cracking truecrypt volumes. That notice on the departure announcement has been taken to mean that if a bug is found in truecrypt, they won't be there to fix it. We can't be 100% sure, but if you have doubts, go take a look at the source code.
Q: But how can I trust you?
A: You know, if the NSA was that capable, they probably would have removed that thought from your mind already. Hypotheticals aside, there are potentially millions of eyes looking at the code, and word can spread across the internet faster than it takes for you to access the internet, so even if law enforcement was on full steam, they couldn't stop someone from reporting a hole in the code. There's even more attention in this direction because of heartbleed and the NSA leaks.
