[galaxy-user] How to determine version of Galaxy from main page

Hi folks, I've researched this in the new global Google Search tool http://galaxy.psu.edu/search/web/ but didn't see the answer I needed. Is there actually a single "version" of Galaxy ? or is it a collection of components with their own versions ? Can that can be seen on or near the Main front page ? I can't see a Version/About type of item, either in menus or lurking in some rev stamp at the bottom of pages etc. Thanks. -- Greg Edwards gedwards2@gmail.com
