Is there a list of all cryptocoin currencies? Apart from bitcoin, I know few other crypto currencies (by this I mean currency which works in a similar way to bitcon). They are:


namecoin
lightcoin
ripple


I also heard about SolidCoin, but as far as I understood it is already dead.

Is this everything or am I missing something
The bitcoin wiki has a list:

There is a forum dedicated to alternative coins at bitcointalk:
