I use Hotmail also. Still broken. I have made Huddler aware:)
I checked yours and I'm seeing PM notifications being delivered. Check your filters and junk mail. I'll PM you in a sec.
I checked your account and sent you a bunch of test PMs. You had this option deselected in your profile:
I checked that box, sent you another PM, and voila - show it as being sent out. The others weren't being sent due to this setting.
