I got an invitation to join Craftsy but never heard of it until now. Is anyone here a member? It looks interesting, but just don't want to be bombarded by spam if I give them my email address.

Get a disposable email just for them

I've never heard about them.

Is that that the one that sell's classes?

Yes, but it looks like they also have free tutorials. I'm probably not going to join. This board keeps me busy enough. :o)
