ok this is what i got so far.
origional photopost installation is http://example.com/
ive installed forums to http://example.com/forum/
both installs share same database with different prefixs pp_ and phpbb_
I have manually added each account from photopost to phpbb and made the userid's match.
when i go into phpmyadmin and edit registration from photopost to phpbb3 i just get errors. what steps did i mess up or miss. please help. :/
