Do sailors have questions?

I have long wanted to fasten a question and answer engine to my website in order to simplify and expand the faq format that is familiar to many (frequently asked questions). And so, after taking a walk through the search, I stumbled upon a rather interesting “engine”, about which I want to tell a respected Habrapublic.

The script is called Question2Answer and has several advantages:

• It is free and open source, the GPL license, is actively being finalized by the author.
• Easy to install on php + mysql.
• Many convenient features are well implemented: autocompletion of tags, related issues, support for design templates, seo-compatibility, all kinds of e-mail notifications and rss-broadcasts.
• A social mechanism is involved: voting for questions and answers, user rating, the ability to issue "badges".
• Easy integration: you can use the existing user base of the site or authorize your Facebook account.
  

Interested can proceed to the demo site of the developer, in the same place there are all links to download.

Russian localization is available, which is lame when placing cases near the numerals, but all this is quite easily treated, I can lay out my fixes, if someone needs them.

Thus, in half an hour you can install on your website the thematic analogue of stackoverflow.com, which is likely to be highly appreciated by users and has a chance to grow into a good information center, where problems are quickly solved.
