"2013-05-15: UPDATE regarding changes in Linden Lab's TOS
Linden Lab has recently changed their Terms of Service. As a result, we are currently not able to offer our service to Second Life residents. This means that our in-world terminal can currently not accept Linden Dollars from Second Life and there can be no payouts of Linden Dollars to Second Life.
Other currencies are not affected. If you have Linden Dollars on your VirWoX account, you may still exchange them to another currency and request a payout.
Good News: Linden Lab has approached us with a potential solution that would allow us to serve our customers within the bounds of the updated Second Life Terms of Service. We are in discussions with them and look forward to being able to share more information very soon.
Please refrain from sending us support messages about this issue, at the moment we will not be able to give you more information. Thank you for your patience and understanding."
