Welcome to Librarium Online!
Like others I have been lurking about for a couple of months. I finally decided to create an account because I am getting back into 40K.
I originally started playing in the Rogue Trader days and have gone through every edition since. When 4th edition came out I pretty much put up all of my 40K stuff and let it collect dust. Recently however I have been bitten by the bug and decided to brush the dust off and start playing again. The armies that I currently have are the Imperial Fist, Tau, and Eldar. I will probably get rid of my Tau forces but I think I will start up my Eldar again seeing how they have a new Codex.
Anyway, I could go on and on but I won't. I hope to learn good things from everyone and be able to contribute in my own way.
Welcome to LO, good to have another Rich on board! Have a read of the rules (found here), and then get posting. Good choice with the new Eldar codex - I really like it. Have you decided which craftworld you are going to collect? It sounds like your a veteran player so you input on the forums should be much appreciated.
Have fun buddy, see you on the forums.
