hi, I have just registered (with help from Karajorma, at the end I needed to have my authentication and password setted manually).
I tried one day ago to register, and I did not recieve any authentication mail at all. i have checked spam and so on, don't worry.
I also tried to send myself another authentication mail with a page (that I cannot find again, but it is there).
I also tried to register another username, kuaki, with a 10minmail, and it din't work either.
maybe it has something to do with the Diaspora release, maybe it is overloaded?
this is really bad, right now a lot of guys are getting into the forums because of the diaspora release, and if they cannot register it's a pitty :/.
