I got a heads up from Thom, mentioning that he was having trouble with certificates on the mumble client on the beyondbitcoin server.
I've did some testing with a couple of others where we repeatedly tried registering through android and other pcs with different certificates and names, but we were not able to reproduce the problem.
So if people are having issues could you list them plus the steps you took for them to occur?
Keep in mind, the mumble certificate is like a public/private keypair and it will replace the password you have to use the first time you login to the server. After that the certficiate is used instead of the password to login and encrypt traffic. This also means that only one identity can be logged on at the same time with the same certificate. Also you can't arbitrarily change names when you've registered yourself on the server.
Should you want to change/retrieve your name give a shoutout to either Fuzzy, JabbaJabba or me to remove the registration from the server, which will allow you to reregister with the name you'd like.
