Yeah, it happened around mid-March (see: e.g. https://github.com/fifty-six/zig.SteamManifestPatcher/issues/10), though the guide still mentions it. Guide will probably be updated soon enough

Hey, I was messing around with the messaging system in its infancy and sent a few messages containing pretty large payloads. Me and the person I was messaging noticed that the site feels like it's constantly under pressure. When checking the GET to the root domain, I saw that the response contains the messages. As a result, loading the site causes a load of >20MB of messages and slows loading to a crawl. I've heard a few others have had issues after sending similarly long messages. Is there any chance this could be changed?

no

haha yes
