adding tab button to "find all posts"
 

I want to add a tab button where users can get a list of topics they posted in. Now they have to go to their profile an click on "find all post"

adding a tab button is easy, but which link/url do i have to put in?

This is from the memberaction_dropdown template:
Just change the variable from $memberinfo to $bbuserinfo and you should be OK.

How can editing a template can make a tab button?

I edited that template but i don't see any change? btw there is no '$memberinfo", just "memberinfo"

I use this mod to make a tab button https://vborg.vbsupport.ru/showthread.php?t=228507

I don't know anything about that mod, sorry.

Yes, it says "memberinfo", but it's really a variable called $memberinfo.
