Sorry to see you go Andrew. Surely, if things aren't right here, then walking away wont fix the problem? Isn't it better to work to sort out those issues rather than drop them? Even with the problems you mention, this is still one of the better forums on the internet (at least, it is compared to the other ones I visit).

And if you think there are too many Microsoft Ads - then you've only got to take one action with them. Click on 'em! Microsoft are funding the PPC (pay-per-click) programme - they're unlikely to present anything that you'll want to buy, and you just get to raise a bit of cash for the forum.
