Why shouldn't you? I'm not sure about .xxx. I wanted a teeshirt, they said they were going to look into sending me one. So I'm not really supporting them till i get the shirt. I don't think I'm getting one either.
Now as for Paxum they have proved to me that they are a very good and well organized company. A few months ago my MasterCard had a technical problem where i couldn't send payments from my checking account to the MasterCard account. It took 5 or 6 day's to fix but in exchange they refunded my 44.95 AND paid to have the cash wired to another countries bank account as their product was not working properly for me.
Now streamate on the other hand...
