Cpr is a global moderator here though doesn't post much these days.

James MCdonald doesn't visit here regularly anymore, but he's doing very well I presume. You can follow him on twitter @jamesmcdonald

Sam Granger is very busy with work offline but still goes on msn once in a while and visits here occasionally.

Vizon was banned a few months ago for doing some VERY bad things to TFL, I think he put TFL offline and redirected it elsewhere? However, I don't know the story well. And Craddock has his personal projects but doesn't come here often.

That's it really for the names you gave, hope that was helpful.
