The Glyph Exchange mods have confirmed to me that they have no interest in restarting on this website. Not because of anything against Lemmy, but because doing it a 3rd time would be overwhelming for them.
The Coordinate Exchange is the old one run by a mod who did nothing to build the subreddit, then returned after 4 years and kicked out all the mods who actually built the subreddit. If that mod started one here, I would not support it, since his actions are almost like a scaled-down version of Reddit's actions.
So, if we want a Glyph Exchange here, someone will have to volunteer to run it. A lot of people have expressed a desire to see the old fractured Reddit NMS community unified into a single community on Lemmy, and I think that might be wise too. Especially since Lemmy relies on a search function rather than flairs.
