I think I got myself banned from there as well. I was spamming a bit too much. I don't know if I was because I left as soon as I did it. I'm already on here, so I'm not going to take any more chances.
This also means anything I share that's SMBX related will be for the 38A version. You are more than welcome to make masked versions of my graphic submissions for any versions of SMBX that use sprite masks. Please just let me know.
