Please post here if you encounter any broken functionality on the boards (eg, problems with posting in a certain area, issue with PMs etc), or any suggestions/questions that might make the message boards easier to use.
Some of the things I've identified that need fixing:
Receiving Private Messages will very likely break the layout (haven't put the code for the banner etc in for that section yet).
A couple of the small button images ("WWW" button if you have a website in your profile; "warn user" [visible only to moderators]) do not match the rest of the theme.
Because there are dual side menus, wide inline images in posts will cause overlap of sections. I might put a width limit in place for them (larger images will need to be incorporated as attachments instead), but users with resolutions <1024x768 will still get occasional glitches of this type.
