I don't know if you know this already, but I thought I would let you know. That validate emails doesn't work. I created yesterday two accounts, and I didn't get a validate email for them, and not when I clicked the button to send out new ones out either.
Btw, you're doing a great work with the site. Just hoping that scribbld will get a new server soon and more bandwidth. Are you planning to change the number of icons for the free users when the new server is up? Or will it just be a choice to pay for more in the future too?
