There are a couple of choices still out there for people that want a matched betting forum. MSE and Oddsmonkey are useful, but out there on it's own is Profit Accumulator. There's no better place for a newbie to start. Once you've got the basics down you really only need it for the new offers, but that's still worth the membership fee.
I'm a little sad about this, as the best part of The Gambling Times was the people and the community, that's harder to get on a larger site, but first and foremost matched betting and advantage play was always about the money, so guess I'll have to get my witty banter fix from friends instead!
