Thanks, hcgtv. I tracked down NP_PunBB , added and filled in the options in Nucleus. But Nucleus can't verify and login users already created in PunBB table. I recalled somewhere in the thread that this is indeed the case. If so, do you know if anyone has released a new plug-in to remedy this? (I've seen many phpBB-Nucleus integration plug-ins; only one punBB-Nucleus so far; but for now, I'm sticking to PunBB).
Thanks in advance.
