Several years ago, I raced online quite a bit, but then real life
intruded. I want to get back into it now. Where?

A lot of the links I'm finding are dead, so I need current links to
addons, active league(s) preferably with handicaps, etc...

Also, how fast to I need to be in order to be competitive? I'm racing
F2 right now, and my GPLrank is +389 :-(
