I have yet to see that, really.
And I have already had several people simply *give up* on joining CIYAM Open due to GPG - really!
(perhaps I should refer any future such people to you to get them somehow magically converted?)
It isn't magic, I just know how to teach GPG, which includes pointing them to software that will make it easy, what they will need to know in the command line. I really don't understand how they gave up GPG isn't a hard thing to learn to just use.
I actually taught a person IRC and GPG for bitcoin-otc and they gave up trying on their own, after I explain and held there hand showing them and explain exactly what they need to know, how to use it and what references will be a great deal of wealth to them.
Also If they are giving up that means they are probably frustrated and sometimes it is the teacher that can cause that.
