Now, I'm not sure if this counts as programming, but a while ago (before I left) I found an MMORPG maker, called Eclipse. You can SadScript to expand on the engine, or open up Visual Basic 6 and edit the source code. It's open-source, I suggest using Robin's Eclipse Origins edit.

You should go there. It's a http://www.touchofdeathforums.com]pretty nice engine for beginners. No, I am not advertising, I'm telling you about it with a link. ;D
