Man Brinksters support sounds horrible.  The mgmt here should come down hard on them.
Brinkster has lots of MS connection but so does DNN. 
The DNN folks should ask MS to put some pressure on them to get their act together.  And definitely dont let Brinkster advertise here.

I admire your persistance, dont give up.  DNN, with its quirks, is worth it.  Unless you feel better paying somone.(like brinkster) :)

IM not saying you should move your site but maybe for a few bucks you could try it. Lots of hosts have trial periods.  Its really not that hard to move a site to a different host.

Like to know how it worked out after the move.
