Ok people, the final version of 5.1 has just been posted. Check the CHANGELOG
for more information on the updates and fixes.
There is now a stylesheets folder that needs to be moved into your HTML tree upon setup and a new config variable that needs to point to this folder. You can put any stylesheets in this folder and make them available to your users. This allows you to totally change the look of the forum with a click of the button. They basically work like skins for the entire program. There are several default stylesheets that come with the distribution which you can demo here by editing your display preferences.
I will be setting up a stylesheet repository in the resource center for those that would ike to contribute some for others to download. I will also be adding many of them to the default distribution, like maybe some holiday skins, etc.
