Alright, so I asked Avaritia (Latias), our supreme not-so-supreme head administrator about the custom pokemon and another method of executing them. She agreed to it, so as such, the custom pokemon sub-forum is now opened again for posting and custom pokemon creation. You won't be able to see any of the old customs that were approved because they are in a hidden "Recreation" sub-forum that only administrators should be able to see. This is done because they will have to be recreated or otherwise modified to fit the new standards, and as such, they shouldn't be clogging up the approved forum until they are approvable.
Thank you for your patience, and look forward to various customs popping up as they are revised and fixed up.
