In a few short hours (and with no previous experience of XF's ACP or template/file system) I've managed to install a skin (thanks Erik), change the default editor icons for some different ones, add new smilies, add new forum-read icons, placed my Google ads where I want them, add a site logo, and set-up user/moderator permissions and open my forums.
Fantastic. Well done chaps - keep up the good work.
Oh, and did I mention the site name was GeeksChat.net? (lol)
