That's essentially what the Search function does.
Skizo Am sorry i should have put more info well
2nd pic write any thing you like and it give you 3 options to search before makeing a thread like what i have done in this pic, am looking for Hard drive testing
Hit the Button and it pops up with the thread found like this 2nd pic so it makes everything easy for everyone, i think this tool will be usefull to fst
But you can make it with out the pop up it be much better. p.s using thse search function in the thread will help us and other people. That's why i made this nices Suggestion.
Like Skizo said, that's what the search function does.
The search menu is only a few inches above the title bar and has all of the same options so I don't believe it's worthwhile to add this.
Maybe just a note saying to use search before posting would make sense.
