Maybe it's the one called "MagicDoors" from the Cave Story Tribute Site Forums?
He usually goes on anonymous at the CSTSF. And he's posted screenshots about the Cave Story reskin there, whilst Mvskoke posted the link to these forums...
another one of the forums I moderate! ^_^
Another of the forums you moderate? You moderate more than one forum?
Two as global mod, One as only a single forum mod. However, that last one is the only forum on the site which gets any action, and it doesn't even get much of that atm. It'll pick up, though.

Strangely enough, I'm not surprised. I'm supposed to be surprised yet I'm not. Guess waking up with a head injury that was accidental due to
being brutally murdered in a nightmare at 5am (South African time) isn't good. 1003 head injuries in total.

Well, if I somehow find it I
won't make about 25 posts a day. One of the reasons that I've got post-banned at the CSTSF. But I was sort-of bored... because...
I forgot what I wanted to do. Mod all
four CS mods I have. Yeah, it increased by one a few days ago.
Also, I won't make a CS Mod thread without permission, because it's related to CS and bumping the ancient CS thread would mean trouble. I guess.
Yet.
