It is like this.
1. If you select vb3 integration you need to do this.
a. change the info to vb3 integration like I stated
b. edit your usergroups table for Photopost in phpmyadmin. Delete every entry in the usergroups table except number 5 which is your admin insert. edit that entry and change the 5 to a 6 so your vb
admin login will get an admin link.
c. You would login to photopost with your vb3 login
Your users in photopost images will not belong to the right person afterward though so as an admin you would need to reassign them to the proper user in VB
If you have trouble integrating things we do offer installation service for 59.00 which would take care of integrating things all except for of course the orphaned images which would be on you to edit and reassign.
