I'm such a goddamn fool:D
Today morning I tried it 3 times and it was always invalid, now after reading your post I gave it an unbelieving try.... Worked like charm.
Copy and paste seems to be hardest obstacle:)

I want a 1 week Gold key!

Kindly read the rules :)

Registered users, who made 200 posts and gave 500 "Thank You" and can ask 2 hours, 6 hours, 24 hours and 2 weeks Gold Keys!

Could I grab a 2 hour key from someone? Thanks.

Any size key would be much appreciated. Thanks.

2 hours Gold Key sent, sponsor Mohanrao

2 week Gold Key sent, sponsor Baloo1466

Is there any way for us to check if the key still valid or not...? ( Only for check, not for activated )
Maybe there's feature for that...? Need to know about that, thanks :)

Thanks for they key but it has already been activated by someone :(

Do you happen to have another?

Unfortunately, no. Only to try to activate it. Or ask key donor:) (he/she can see this at his key page)
