I'm actually curious to be able to use it in conjunction with other features of the search (eg only seeing posts in specific subforums).
That was the problem I was running into, and was hoping there was a solution.
In the search window, I can select certain players, and I can even select certain sub-forums. But it doesn't allow me to do a blanket search. I still need to put
something into the search field, and if I don't know exactly what I want outside of "posts by the selected user(s)", it doesn't seem to let me. It doesn't accept a blank search query.
