My suggestion is simply an Icon next to your name, similar to a "Party Finder" Icon or "Readying Duty" Icon, an Icon that simply displays you seek a TT Match.
Just the Regular "Battle" icon except Blue or Green could work well.
If there is one and I'm an idiot then.. oh well... oops. But right now I just use Party Finder and my search comment, doesn't do a lot of good though.
