Jabber looks to have a lot of different clients to suit multiple tastes. Found an old entry for myself with a the e-mail address I since decided to keep private for spam avoidance reasons. As an educational experience, and with the help of stpeter, I deleted my entry by typing in the raw XML:
<iq type='set' to='users.jabber.org'>
<query xmlns='jabber:iq:register'>
<remove/>
</query>
</iq>
It seems that everywhere I turn I find old friends. James Barry and I have crossed paths several times related to both Apache and IBM.
