One quick difference I found between the two themes: the OpenSUSE-Forum theme has a place in the User Control Panel to change your displayed information (like location, ect…) and the OpenSUSE theme is missing this page. There is also a few small differences between the two panels, which has some links missing in one, and not the other: such as the friends page. Not a huge deal, just wanted to let you know.
Thanks for the report. We’ll eventually get them in sync. To tell you the truth, the openSUSE template is a bit older and we haven’t focused any effort on that because we were banking on the openSUSE-Forums template. Now that I know some folks like the other one, we’ll work on it.
