If you’re having an issue you may wish to visit the forum to ask fellow users for advice. There’s always someone around waiting to help newcomers, so for questions that need answers, that’s your first stop. The forum is probably the best place to get help.
You may also wish to drop in the chat room, which is #raspbmc on Freenode.
If you wish to contact the developer of Raspbmc directly, you can do so by either tweeting me @SamNazarko or emailing me at samnazarko /a\t/ stmteam.com
