This is exactly the case. We are migrating everything over to a more secure platform, but currently though we are limited on devs and limited on free time to be able to work on this.
We might be gone awhile but we (staff) all have agreed to try our best to make sure
UGC doesn't die completely.
First we are working on the backend and making sure everything is tip top, and then we will be (hopefully) migrating over all user data and tables, and then it's a bit of housekeeping and tweeking.
If you would like to keep up to date on what is happening you can join our
IRC as I will be posting updates when we reach milestones in the migration process.
Cheers.
