Hello
I was making "anonymous" very minor edits for some months and finally got around to signing up with an account. My editing is very limited and continues to be minor so far.
I've used Wikipedia as a reference for several years. "What links here" and "External Links" are very handy.
"Recent changes" and "Random article" are neat features which take you to subjects you'd never purposely seek out. I've stumbled across some interesting articles and topics this way.
