Thanks for your reply.
That's good to hear. I read on some post that there was some trouble
with autoincrement, primary index fields. Something about the
internal counter not updating correctly and not letting add any new
records because of a duplicate key error.
Glad to hear that someone has already had experience using it with so
many users and that it works as expected.
Thanks again for your comment.
