Am I allowed to submit runs using the Steam version of Sonic 1 or 2 using a Sonic Classic Heroes mod from the Steam community?

I see that PC is listed and I assume that's ok, but I wanted to check to be sure.

As of right now, the game is pretty inactive, and it probably will be most of the time, but I'm bringing up the mod issue for this game.

There's only 1 moderator for this game and when I look at their account it says they were last online 9 months ago. I tried contacting them through all of their connected social medias, but none of them exist except Steam, which I couldn't make contact through because it wouldn't let me message them without being friends on Steam, and my friend request was either rejected, blocked, or there was a Steam glitch.

There are 2 reasons I'm bringing all this up, the first being that I submitted a run a month ago and it wasn't verified. I'm not sure what you're supposed to do when a game's mods are inactive and you can't contact them, but that's one of the things I'm asking about in this forum post. Might have to contact site mods to help if no one can contact the current mod.

The other thing I have to ask is, while I myself would like to volunteer to become a mod for this game, and am wondering if anyone else would also be interested in being a mod here. Games are usually better when there's at least two mods so no runner has to verify their own runs (because while I doubt anyone would cheat at this game, it's just better in my opinion if runners aren't verifying their own runs, keeps things more ethical).

So yeah, game probably needs contact with speedrun.com's site mods to revive activity for the game (if no one can contact the current mod), and if that happens, I don't want to be the sole mod of the game (if I even need to be), so if anyone here is responsible enough and knows the game's rules, you know what I'm asking here.

The Maw does have 3 DLC levels, and I was wondering if we could get those on the Level Leaderboard. The levels are named Brute Force, River Redirect, and Speeder Lane. I was also thinking we could have a category for Any% With DLC (because if I remember correctly, playing the game with DLC implements the DLC levels directly into the story). I we had that we could also have a 100% With DLC category.
