Webpage builder is fine, it also looks professional once you got used to it . Anyway, just send me a message once you are done discussing about the website 
.
. Discussing that here would be fine, I think. For it is not really of topic, and it is for the betterment of this Charity Program.
This what I suggest for the domain:
www.bitcointalkcharity.org
www.crytpocharity.org
And I think, we should go for the .org because sooner or later this will become a large group.
