I will only add the latest style cygnet is written for phpbb3.1 and ROCKS
after using it for testing im begining to wonder how im ever going to like 3.0 again .... rocket and phpBB sure have done well
the only downfall ive found is a lot of extentions this customer needed have not been written for 3.1 yet or are in very early development so we are tossing up with just going for phpBB 3.1 with cygnet and ignoring the missing extentions (no longer called MODS) or installing a rocket 3.0 template and reinstalling the missing mods (yup 3.0 is still MODS)
My real advice is think very very hard before upgrading to 3.1
I would wait until rocket sort out the latest Gantry and employ their funky tricks no other style has ever thought of (Cygnet rocks) and also waiting for phpBB3.1 extention writers to complete their addons
Thank you for the reply Reggie, I'm a little disappointed to say the least, because I like the Chimera theme, but I understand that there are a huge number of changes between 3.0 and 3.1 so I completely understand your decision. I suppose I'll just have upgrade when I have the finances in place.
