There should be a link somewhere in the main forums page that directs you to a page where it shows the recent threads you've participated in. It makes it easier to follow up on.

 

Just click on Thread Tools on the upper right corner and select subscribe. Then delete them later when you get bored or don't need 'em anymore.

 

click on your name... and click "find all posts by user"

 

I still say the original posters suggestion is the best. One simple button like other zero forums etc have.

 

lots of ways to do it click enter forum and seach for ur name should bring up most or click ur name in here like robertk said and click find all posts or sign ur name after everypost and u can just search ur name and it will come up..
