Forums are great place to meet new people and get valuable information. I am apart of a couple of really good forums and I thought that I would share. Some of you already know, but for those who don't, well you now you do!
Absolute Write Water Cooler: This is my number one best site. Everyone is extremely helpful and the resources and connections obtained are invaluable to a writer.
Kindle Forums: This is good site to for information and learning. This site is a little more confusing to navigate, but once you get the hang of it, it is an awesome site.
PubIt: They have a forum, while I find it confusing, some people like it.
WritingForum.com: this has the same setup as AW (First on list). I am new to this one, so I will have to get back to this later.
Yahoo Groups are another valuable site to meet other authors and gain information.
Feel free to add to the list if anyone can come up with other good sites!
