In our effort to bring you a great new release, we have overhauled setup again. It should be easier than ever now, checking a lot of requirements and featuring a new dynamic module installation mechanism.
In addition to that there is an uninstall option now, for those who don't like more.groupware after testing it... :)
If you can, please a snapshot on/after the weekend and report bugs to the tracker. Translators should have a look at the language files (not only) for setup, as a lot of strings have been added or changed (sorry...).
