I used to just pop on here to see if there was anything in the account alerts... since the new forum came online, I don't get these anymore; I need to remember which threads I replied in, and manually see if anyone responded. Might be frustrating to people who post a LOT of stuff and are waiting a response, or like to help others. Perhaps it's just me?
I had this EXACT issue ... till I found the your posts link.
I use it now as a quick indicator to see in which of the threads I replied are messages I havent read yet. (blue icon) or, in which threads I replied at all.
In the old version, when I did a search .. generally round page 2 or 3 (when checking posts) I got the search time out thing and had to search again and click to the needed page.
Now it works perfect. (searching your own posts history)
