Custom Header Graphics
There is a new variable being used now to specify the header text. It is %WEBTITLE%. So whereas in the old wiki you had to provide a graphic with your title, you can now simply add
* Set WEBTITLE = whatever you want the title to be
to your WebPreferences topic. If you have an existing WEBLOGO graphic with the title as part of the image that you don't want to change, you can use
* Set WEBTITLE =
to clear out the UM Wiki from the header.
For even more customization you can now create a topic named WebTopBar in your Wiki Web and completely customize your header.
