Thread:Project:Support desk/Add users using php login

I have created a site where there are 3 main sections, 1 is content made by the users, 1 is mediawiki and 1 is phpBB, however at present each of these sections has their own registration, I have made a custom email confirmed registration for the users section, but I would like to input the values into the mediawiki database and phpBB. Any help, ideas how I can achieve this?
