ejiki: Does this mean that you have different results for your account? Indeed, strange feature... I posted about this button because it works for me all the time, and I'm sure I get all threads (I remember the first one), but I'm new here, so maybe it starts to work in weird way when user have posts over some limit...Or maybe it's some time limit...
I didn't bother to count the number of threads displayed yesterday (though the overall length of the list feels about the same based on the scroll downs I had to do to reach the end of it), but I noticed today that a thread that was listed as third or forth from the bottom yesterday sits at last place now.
IIRC, my first post was sometime in early 2012, but the list starts at mid to late Dec 2013 - that's about almost two years of posts missing. That definitely makes it time-limited (just like the "My posts" page is).
Ok, I just tried it again after having posted in a few threads today. The button disappeared now after 17 clicks and I get 90 threads listed, but still only onwards mid Dec 2013. And now the last thread listed is one that was updated yesterday (though I myself posted in it a very long time ago and only once) while older threads are listed higher - so, the order is not by date, maybe just random?
And I just remembered another thread I posted in during the Winter Sale that's missing from the list.
I'm too lazy to look further into it - frankly I never used this list before and it seems to have been a wise decision given its inconsistent and unreliable results ;-P
Either way, it's a pain in the butt to try and find your posts using this list, especially in threads that get a lot of traffic.
So,
this wish here is still valid and it needs more votes.
