Thanks for this comprehensive list
I am actually already a member of a few of these forums.
Apart from the advantage of do follow on your links, they actually have people sharing some really useful information
You search for anything and the first result is digitalpoint.com, makemoneykingdom.com, sitepoint.com so on and so forth. so it’s good to have your links there and its threads gains PR pretty fast if your thread goes long

This is almost exactly the list I was looking for. I actually posted a request in a forum the other day, but then stumbled across this post. The only other bit of useful information to have would be which forums require a “minimum post count” before allowing your signature to show up. Thanks again for taking the time to compile this list.
And Finally, Please add my forum to your list? We are Dofollow and we allow Dofollow signatures.http://www.makemoneykingdom.com
