At ANY website, simply write more than a 3 line profile and be honest about what you want and are looking for and put any personality "quirks" at the bottom. Less than 10 Percent at any site will read beyond 2 or 3 lines. People who READ ENTIRE profiles are the serious ones.
Having said that, even W/O any quirks, finding "compatible" women at any FREE site is like trying to catch a fly with chopsticks. The "free" part IS the catch.
