Posting gametypes on 7s will only net you 10 downloads or so from what I've observed. Nearly all of the downloads come from YouTube, reddit, Halo content producers, and the weekly most downloaded/liked gametypes list in-game.
The database has moved over there and is being linked to from my YouTube channel. The database thread over there has almost 1k views already and it was posted 2 weeks ago.
7s is BIG. There are countless other sections which get more views than the Halo section.
I think the significant difference is that over there it's mostly 'release style' posts and there's a lot of non-retail-compatible stuff interspersed. A '[Retail] Gametype Modding Discussion' thread would probably make a difference though. I mean unless there is one that's just buried.
