The Sports Exchange will remain open. But this means that the awesome even money teasers Mansion has been offering are no more

Here's the blurb from sportsbookreview.com:

10.16.2006 (09:59 AM CST)

Mansion (SBR rating B-) closes its sportsbook and casino to players residing in the US. Mansion’s most popular offering is its low-margin sports exchange betting platform, which will remain open for all clients. However, management tells SBR that they will no longer employ market makers to seed the exchange and there may be a substantial decline in wagering activity. The company aims to offer true peer-to-peer trading. SBR has downgraded Mansion to B- due to customer service issues, reduced offerings and complaints of canceled wagers without alerting players through email.
My other site, BetWWTS, has frozen US accounts. So glad I got my money out of there last week!

Betcorp Freezes all US accounts
The Betcorp Group, which includes WWTS (SBR rating C-) has frozen all accounts belonging to US residents indefinitely. SBR has learned that the company has taken this action in order to facilitate a sale that would put the sportsbooks under private ownership. Players can expect to be locked out of their accounts at the start of the business week.
