I'm using Postgres v8.4, Apache v2.2.14, PHP v5.2.11. Not exactly sure what version of phpBBv2 we are running. Converting to phpBB v3.0.7PL1 This is a local conversion Batch size of 10000 Inserting 100 rows at once @set_time_limit(0); @ini_set('memory_limit', '256M'); @ini_set('upload_max_filesize',...
Are theses two webpages on the same site? Is the staff pages php or html? Your best bet if the staff pages are php and on the same site, you can include phpBB in the staff pages then do a couple sql queries.
That sounds like quite a challenge, I don't think this can be done easily, as google groups would most likely be proprietary (Unique system of storing posts and such). You can try asking Google for some help, although I doubt they would be able to help.
Your best bet for this is to create a style for phpBB, to make it look like your web design. Look at the Styles forum(LINK). Really, to add the overhead buttons you will need to edit overall_header.html.
