That's a good idea. There is the
Manual. But something like you said would be nice too.
Maybe it could include:
1. How to change the logo and edit the main menu in overall_header.php
2. How to protect users email addresses (by enabling email via the board)
3. How to find and install Styles and MODs
4. Whether or not to use Gzip
5. Ways to integrate the board with your site, such as a common login, etc
Is that the sort of thing you are looking for?
and mstark, you move those posts while logged in as admin or moderator, the links are at the lower left of the last post.
