All I can say is...
This is so incredible, I can't even say. When I installed Ptirhiik's latest version of his Categories mod, 2.1.6, on my phpBB2, I was boggled by the new format. When I installed a phpBB3 test forum, my mind almost exploded. The first thing I noticed was how user-friendly the format was, and then how comprehensive the options were. Then I found out that Olympus had a category hierarchy. All I have to say is
That was the perfect idea. I love Ptirhiik and Cr@ter$ to death, but having all that separated stuff was getting confusing. I just hope lots of the older style designers come back to update their styles for Olympus.
Mega kudos to the team! Great job!!!
