Hey! You should be able to click edit title, then change the category to “Community - Devlog”
Yep, you can. But (sadly) in exactly 8 days you would log on to realize you can’t change it anymore, as your 30 days to edit it are over! GDevelop locks posts (for you since you are trust level 2) after 30 days. This made Devlog/Megathread posts very annoying, as they pretty much were unusable. Thankfully, I convinced Bouh to allow them if they are in the devlog catagory, so putting devlog on your post allows you to edit it whenever.
(You can see the conversation here: New Megathread Category Request)
