Using the free capped gives me full speed on nntp...no idea what you're talking about then seeyou. When did you use their product? I ask because things sound like it changed. I'm certainly not seeing what you've experienced.
I'll give home pro a bash next month and see how it goes. Though be damn sure I'll pop right on here and apologise to you if my account will indeed be as shaped as your experience was.
I'd love to get to the bottom of this then, but as I said, WA were no help there. I tried the account today, and got the same shaped results. Would you mind pm'ing me your nntp server settings? Just need the port and whether or not you have ssl enabled. I'm wondering if I've somehow landed on a combination that WA are shaping. I'd have no problem admitting fault if that turned out to be the case, and WA offers far more bang for buck in terms of gigs/Rand.
