Hello! I wanted to let you know about the Participated Thread Avatar that Proboards has in their Plug-ins. On Xenforo, when we reply to a thread, it puts our avatar next to it. I love that feature as we are on so many forums & I honestly cannot remember which I replied to lol This is a way so members can see at a glance in a board which posts they have replied to. It's different than the Participated button.
If it's not for you, no worries. Just sharing a feature as it was shared with me
