Somebody took my name on there is there anyway it can be deleted or whatever?? now somebody can impersonate me etc.

First off.. Mibbit is the client you use to connect to the IRC network that we use..

In order to secure your name you have to register it there.

/ns register password email

THAT HAS TO BE DONE ON THE IRC SERVER WHEN YOU HAVE ACCESSED IT.

After that, subsequent log-ins to IRC (Using mibbit in your case) you will have to identify with Nickerv.

/ns identify yourpasswordhere

Use a password you remember....

Also feel free to mail HelpDesk about stuff like this or post it in the Help forum.
