There is a new mod who is in charge of answering your requests of changing your fanart entrance galleries. Dreaming Wolf couldn't do it anymore, so if you requested a change lately, you will have to request a change again. (Requests can be done in the fanart send page -> "Manage my gallery")
The new mod is Spiritgal304. I hope he will do a great job! If you have any questions, contact him by PM.
