o.k.
so let's check another idea.
a) does it make a difference whether the
vb forum and/or PP is in maintainence mode while I use the script or do the sync for the usergroups?
b) What happens with PP usergroups if I would use the import script as delivered by you and change afterwards the UG-ID in the PP-Database to match the UG-ID in vbulletin?
Would this crash my PP install or bring out wrong results?
