I started with phpbb when i was 14 years old and after using it for 1year, i decided to use IPB and vbulletin.

if u want to learn something then u should use phpbb first.All the forum software has its advantage and disadvantage.

If u have desire to learn, then you will like all forum software..

My fav is vbulletin 4, because its very easy to use and code..
