Ya I sent an E-mail out and I'm hoping they are just having server problems. Problem is if they are having server problems sending an email to an @luckyflop.eu address is probably not going to go through. I'm really hoping they didn't just shut down the server and take the BTC on any account that didn't have time to withdraw.
This is the only contact info available. You could try to send a pm to the OP, hoping he registered different email to his forum account. Doubt that will work tho.
Bottom line is, if the admin is honest, he'll bring the site back up and allow withdrawals. If he's not, contacting him won't help.
Hope you didn't have deposited much there.
