Life happened and Shelly lost interest in the Sonic franchise, which is why she ended up just quietly disappearing from the site.

As for making the site like it was... there are so many factors to that that are simply outside our control. For one the Sonic fandom as a whole is currently in a lull, because since Generations there hasn't been a truly solid Sonic game.

I'm not comfortable with the Discord chat or frequent wiki discussion happening off-site either, as it feels like a disconnect from the wiki itself. But it's not my choice to make; people have to feel like the costs to a Discord chat outweigh the benefits in order to move away from it.
