you're right the user ID's have marginal changed
first the nummdering in dcf was e.g. 100002 and in vB3 it's 2.
Also due to the existenz of standard users the numbering is changed.
if the user had 100002 he has now 5; that means all ID's in vB3 have now the new format and +3
any idea how to fix that?
EDIT: I've seen, vb3 is storing the imported user ID in the user db. Does this help?
