thank you man but specify in the documentation that the keys can become obsolete for such as I xD although I took the key from here http://keyserver.ubuntu.com/ . I have some problems but more about this later
I've created a forum to replace an old phpbb forum. Many of the old users want me to import old posts/thread to the new one. So, I want suggestions how I can do that. Perhaps manually if it's a good solution.
