I love those who can get the portal working on phpbb3. I tried it once and it didn't work out too good so I had to re-install phpbb3 from the beginning.
Looks really good... I installed a portal for phpBB3 and it kind of messed up the nav bar as the dot in between the portal link and the next link wouldn't show. I could have fiddled with it but it was just so strange that it had no acp options and you had to edit the files to remove blocks so i decided against it.
This seems much different than the portal I installed for TNG right before we changed to SMF. Interesting...Well, your portal looks very nice, although the login at the top of the tables is kind of annoying.
