I have only been on EH for a week or so but have been lucky to get quite a few matches - as such I have had to introduce some pretty strict personal filters when I am reading someone's response.

1. If no pic, then no com: why - because honesty is key and I think that showing your image is part of that.
2. Things I can't live without - anything that smacks of materialism/superficialisim : car, phone, flat, ipod; lipstick, shopping etc...
I know that the car might be to aid communication or meeting people, the phone for similar or to stay in touch with a sick relative (if they qualify the must have then that is different) but being attached to things is a real turn off for me.
3. If I do send a communication and then get no answer within three days I will close the match unless she lets me know she will be away - I especially close if my profile has been viewed but no answer to the com.

Does anyone else apply these sort of criteria and if so what do you use ????
