Thanks southcogs and GA Boater for responding. What I'm asking about is an indication in that diagram that shows I have posted somewhere in a thread. So when I open a sub-forum, like say "
Forum and Website Issues" and it lists a page of thread titles in that forum, there is an icon that shows which of those threads I've posted in. Most vBulletin driven forums will have a checkmark that shows you've posted (Subscribed) in a thread. In GA Boater's snippet shown above, it will appear in between the paperclip and the "responses, views, likes" part.
In the other vBulletin sites, you are automatically subscribed when you post and a checkmark is automatically shown in thread lists. I see here I can manually subscribe, and manually pull up "my subscriptions", search through that for what I want and then go there, so I guess I will use that path.
Ummm....if vBulletin has been promising a fix for 5 releases for something that other vBull driven sites have had for years..... I know it's not much, but the little checkmark icon seems to make it much easier to navigate.
