Do you mean the small avatar under the thread creator's avatar? I don't remember doing anything special for that. Every thread where my avatar appears at the bottom right is a thread where I posted something.
If you want a list, you can use search, leave it blank and put your username in Posted by member option.
You're kidding me right? That's exactly what I was looking for. Perhaps it's some setting that you need to change?
I just thought everyone would see the same. I've been through all of my settings and couldn't find how to enable or disable that feature.
I don't think that this is manged by settings. @Rasheed187 try to set up avatar and see if it is shown on your active threads.
Even if you have the default avatar showing, the minime avatar will still be in place for threads that you have replied to. I temporarily deleted my avatar and it shows the default one on threads I've posted in. Mousing over it will tell you how many replies you have in the thread. Members only ever see that mini avatar, no matter what it looks like, for threads they have posted in. You never see anyone elses mini avatar in that position.
What the hell, at the moment I am indeed seeing this. So I suspect it was there all along, but I never noticed it. LOL, my bad. You're both correct, but apparently it also works without any avatar, cool feature.
