Please, please make it something other people actually care about. I don't really wanna come off as a bellend for saying this, but I've noticed a couple of folks just posting every little minor change they make with their conlangs to the main subreddit here, and frankly, unless someone is specifically interested in your conlang, we probably don't care - that's what having your own subreddit is for.

I'd like to cite /u/mistaknomore and his /r/Unitican as a great example of what TO do. He occasionally posts a thing onto this sub saying "hey, I've added another 30 lessons to /r/unitican, you guys should go check it out", whereas what I've been seeing from a lot of folks here lately is more like copypasting every single thing from their own subs onto here, almost begging for people to notice them. We're not senpai. At the very least, invite others to compare how they handle the same thing in their own conlangs, as well.

tl;dr: be courteous and make sure when you're making a new post solely to show off something in your conlang, it's something interesting and you at least invite discussion about others's, too.
