I apologize but I thought as how you have been playing from the start you'd know about how you can put up a comment that says what you are interested in doing. there's a broad range different color markers to put next to your name for many different events that happen in-game. you can acess these by going into your search option I believe on your main menu. if not it should be somewhere near there.

Is it perfect.... no... but if people would use it from the start it would be well established by now instead of primarily used by JP and some NA players. I would like it if SE would allow us to search based off of the marker used so you can find everyone interested instead of sifting through names.
