+**Subject:** Permission to post a playtester request?
+
+**Body:**
+
+Hi — I'm working on a custom feature for my 1.21 Java server that involves AI-powered chat interactions. I'm looking for a small group of players to help test it and I think this community would be a good fit since the people here actually understand server administration.
+
+The post would be a short description of what I'm looking for (10ish playtesters, whitelisted server, a few sessions over a couple weeks) with a link to a Google Form application. It's a hobby/research project, not a product or a server advertisement — I'm not trying to recruit a playerbase.
+
+Wanted to check if this is the kind of thing that's allowed here before posting. Happy to share a draft if that helps.
+
+Thanks for your time.
