Any advice?

I have to admit, since having my 2 children, I have gotten somewhat out of the loop when it comes to the best forums and places to find other people's blogs. Does anyone out there have some good sources for me to check out to find sources for me to get more involved in the online gaming community? I am looking for all kinds of tabletop gaming including 40K, historical, LOTR. Thank you in advance for your help.
