I believe I've followed all install instructions. latest wp and plugin. using subdomains multi-site option.
the question is: what's supposed to happen after user ads custom domain under Tools > Domain Mapping. when user from blog http://whatever.mainsite.com goes in there and enters the "Custom Domain" nothing happens. page refreshes and nothing. I feel like perhaps a row should be added in that table showing what the user just entered. but nothing... i just want to know what's supposed to happen so i know if something is wrong.
