To update there is a lot of things that has to be done. Mods and and other changes has to be recreated and that's is to much work. phpbb3 isn't necessarily better than phpbb2 in my opinion so i don't care.
not a problem.
couldn't you put in a phpBB3 skin or is that not possible with phpBB2
try to at least look at the last 10 topics in this (the suggestions) forum before making a new suggestion.
New design is already in the make. You can't use a phpbb3 design on phpbb2.
