This is giving me grey hairs...

I'm led to believe the above link SHOULD show me a list of threads I've posted in (not show me the posts made by me) however it shows a list of posts, (not threads).

I have spent way too long on this already, I'd appreciate any help you can offer please. If anyone knows how to show a list of threads that I've posted in (not just threads I've started) it would be great. Needs to be exactly the same as the "starteronly=1" list but also for threads I didn't start (hence the "starteronly=0" tag)

Thanking you in advance
