If you mean simply placing a free personal ad at like [email protected] or something, yeah, i do and it works quite nicely, you find people that you actually share interests in and you dont have to go through a whole time wasting process of weeding the good from the bad. If you mean an actual agency, well, don't bother, I used to work for one, they wouldn't let you see pics of the people you were going on the date with, and they charged like 4 grand! Fuck that. For 4 grand, they better hook me up with a hot supermodel slut.
