It's easy to say but HARD to do!! PHP --- this thing --- Hmmm --- spent me lots of time to understand and install. MySQL --- this thing --- --- the same result!!! But, if you have made it, you will feel much happy, of course! Since I have installed IPB, it's easy for me to install others such as "vBulletin" and "phpBB". I find IPB really good, really. In my opinion, IPB is better than "vBulletin" and "phpBB". So I suggest you install IPB instead of others.
