Couple of issues with register and webcam

Hey Guys…first off, i couldnt register my email…i think it has something to do with the username before the @ symbol in the email not being long enough. my user name is only 2 digits…3 letters and up works fine…

also, can anyone recommend a web cam app that we can somehow run over the VPN? something im sure that the client and i will both have to install, but that may work better than aim or yahoo messenger. many of the web conferences we have are with prototype parts and the encryption would make he and i feel much better. Thanks
