First of all, sorry about my english, i'll improve it.
My question is:
Nowadays i'm using 2.0.19 phpBB version, and i have some problems with security and others things like read/unread messages(i've installed some MODs, but problems still appears). So, i would like to upgrade my versión to 2.0.22 or phpBB3, i don't know wich is the best choice. What do you thing?
I want to have the same messages on board, need subforums(nowadays using simpleSubForumsMOD).
