Just thought you might be interested in this:

GoDaddy, in addition to requiring a bunch of hacks to actually get MT running which are far beyond the capability of novices, appears to be unable to recieve Trackbacks. I've been back and forth for untold hours with them, wasting days literally trying to get MT to run smoothly on their servers. It works finally, but still won't accept trackbacks.

I would highly recommend that a note to users be placed somewhere saying "DO NOT USE GoDaddy" they are realy a mess.

C'est la vie.
