Unfortunately nope, see here. The button disappeared after 15 clicks and I get only 85 threads displayed. The number of threads seems to be fixed (though varies from user to user) given that new/ updated threads at the top of the list push the ones at the bottom to fall off the list.

Yesterday's and today's testing indicate to me that not only does this work in a limited way, but also in a non-consistent one.

Then I doubt it's really limited, but instead rather buggy.

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.

Sad but true(

Already voted, but there so few votes there that I even don't have a hope to see this feature soon.
By if I could select - I'd prefer "search by username" feature over "my posts", because then I could search not only for my posts, but anyone's too!

Aren't we getting greedy now ;-P

On a more serious note, I can't see "search by username" being implemented as long as a certain other forum feature stays in place in its current form.

The forums need to be replaced entirely be something like Vbulletin.

There are many ways - for example, search query in form of "some_text user:user_name", so, for "threads user:ejiki" we will find all my posts with word "threads" in it, and for "user:ejiki" all my posts ever made. Or, maybe, "search" button could have checkbox "advanced", with extra field drop down when checked.
Hmm... I'm dreaming too much, am I?
Oh please, not vbulletin. It's heavy and slow, while this forum is light and fast (most time). But some features would be awesome.

I was not referring to the search function ;-P
