Ask me anything
As for the matching i did state that they only matched groups of girls with groups of guys. It turns out that i was wrong and you can have two groups of girls or two groups of guys meet up with each other :).
Also someone asked me about cost (which i failed to mention before). They do not charge a monthly fee or anything! They only charge each person $20 and this includes a drink. By paying the small fee it ensures that everyone is serious about meeting up (it would suck to have no shows)
