Actually, they DO apply, I'll help you out with this one:

phpBB3 requires specific mbstring settings which must be altered in order for it to successfully run, thus it can have an effect on Orca if someone was also utilizing Orca for their Groups.

In addition, if someone has integrated something like phpBB3 or vBulleting, then we do need to know as it makes several changes to Dolphin and those of us who have done it can guide them. If you think someone is going to get ANY support for a Dolphin see more integration from a phpBB3 support forum you need to look again. Our Forums are far better equipped to deal with this issue than vice versa.
