I just recognized, that at

-> Groupwise

the version drop down list is offering "GroupWise 8 SP1"?

There I can't see a SP1 for GW8 there so far, and I didn't expect to
see the SP1 that soon - is SP1 out so far? If so, where to download it?

All that's listed for "GroupWise 8 SP1" currently is one beta patch,

Regards, Rudi.
