Tarkus - it's not like the system goes "Oh, subscriber, don't crash".
When WinCustomize.com launched, there were several different skin sites that were quite active. Today, there's WinCustomize and the skinning area on deviantART. The other sites that still exist don't receive the kind of traffic that WC/dA do. So we're having to absorb immense amounts of traffic.
But the # of subscribers we get is pitiful. We have plenty of bandwidth. What we don't have are enough IT people. An experience web programmer (especially ASP.net) or database administrator costs a lot of money. The subscriptions don't even pay for the bandwidth let alone the IT staff we need.
There is no solution other than for us to keep slogging through trying to resolve these issues. The current issue is database related, not website "Feature" based.
Do the math: There are typically thousands of people on the site at the same time. If this site got even 20% less traffic, these "problems" wouldn't crop up.
