Add page markers
 

Adding page markers on threads you posted on so that you know which pages you have posted on so that you do not have to search each page one by one

Can't you just go to your past posts and click on the post you are looking for?

Maybe something like an integer left, right or on top of the icon (envelope/letter) left of the title of the thread. So you know how many times you posted in the thread. Now this case is marked with a bended arrow on top of the envelope/letter.

When you are in the thread itself, you all integer numbers (linked to your posts) at the top of the page, above the posts but under the menu. All these integers are linked to your posts of course. Just like this post is post number three. Then at the top of this page you are looking at right now will be displayed an integer, number 3, linked to this post. When clicking on 3 you go to this post you are reading at this very moment.
