Thanks. This'll make you laugh though...
I filled in the eHarmony questionaire a couple of weeks ago and it immediately told me that I was unsuitable for matching with anyone! Not just that they couldn't match me right now, but that my personality profile was unsuitable for matching ever! After a few moments of thinking "God, even computers think I'm a loser", I sent eHarmony a fairly annoyed email and asked them if they had actually thought about the effect such a message might have on people who have turned to dating services because they have no other option.
I guess the problem for me now is that over 90% of the people I work with are male, all the women are married or in relationships and my friends have drifted away so I get to meet new people once in a blue moon and just don't get the chance to practice my social skills.
There doesn't seem to be many single women in their 30s either.
What do you mean by hotlines though?
