These TQ Forums REALLY Don't Like Hotmail at all.
I hadn't read this until now but not only did I not get to post by changing to my main email address at Hotmail, I could never get validated when I originally joined as Ultimatar because of my Hotmail email address. That is my only gripe. It doesn't like Hotmail.
Thankfully, when I noticed this annoyance, I changed my current membership back to Yahoo, as I joined with, and I'm back. Maybe That is the real problem complications with certain email services. Just a thought.
