I too belonged to a couple different forums and have now narrowed it down to just this one.
Reasons I love it and have stuck with this one:
1} Appreciate all the wonderful/helpful members
2 The way the board is set up is very easy to use....you have no idea how this was a huge deciding factor.
3} The tutorials are awesome-can't tell you how much I have learned, thank-you to all of you helpful members that share so willingly.
I could go on but those are my main reasons.
