I've spent so much time researching the intergration forum pieces around a portal app that wont charge me these additional funds. IE: yearly lease subscription cost for vBulletin and Vportal. vBullentin does not offer half the hacks as phpbb as an instant community.
When I saw the viper alley demo I thought that was right "out of the box" installation. (boy was I wrong!!)
Sorry to vent. but it seems like you should enforce and warn all users to use vb-portal and put a disclamer around the other products.
"It aint easy" putting up with debugging cookie/session problems, global navigation issues, member list and profile syncronazation., not to mention the above subscription / paypal blues.
Its still a great product but the fustration is sooo overwelming.!!
(sorry but I was suppose to go live with my site tonight!!.)
