And how are we not reliable? We've only existed for the past 6 days and we said in the topic title this is a "trial" and we just want to see how things will be running. I admit we weren't prepared for over 600 hack attempts on the server, people abusing the free email service, and mass creation of fake accounts. However, we have adapated to the situation, added extra signup security measures, and have added extra security to the server itself.
If this host isn't good enough for you, then go find another one. K, Thnx.
