Be open to the possibilities
I've found that when using any online dating site, it helps to try and suspend judgement. Some people don't always come across as well on paper (especially guys, who use a minimum of words.) Unless someone is a total creeper or degrades you in some way, give the benefit of the doubt. Make your first dates brief and if it doesn't work out, try again! Dating is all about having an open mind and getting to know what's important to you.
