Roxy,
The shorter addresses became available a little over a year ago (actually it bugged the heck out of me because the MS VFP bug report page would not accept my full email address early last year), it isn't really tied to the browser email access site.
>Yes I have an email address RoxSeibert@worldnet.att.net
>Yes I have another email address RoxSeibert@att.net
>Yes they are actually the same email inbox... the shorter version came when I signed up for the browser-based email option.
>Yes the worldnet address still works, I've switched to the shorter one because their really both the same & everybody was totally confused at DevCon.
