Yeah, that’s right! Now every mod at https://www.ageofempires.com/mods/ has a comment section where you can post and answer comments.
This way you can reach up mod creators with some more ease.
Although much welcomed, this feature still leaves something to be desired. The comments have no notification at all, so you need to get to the mod page to check them. Also, comments and replies can’t get edited, excluded nor flagged.
