Pompster- I've always done ok on pof.
I did meet someone last year off there, he was a lovely guy and ticked every box but he wanted children and I don't want anymore. So it was kind of going nowhere. Give it a whirl.
Sassy I've read the old rules a friend owned it then got the new rules for online dating. I have to say some of it is really good, other parts are a bit cut throat. It says if a guy hasn't asked for your number or maybe it's asked you out after 4 emails then you simply go missing in cyber space, if he's keen enough then he will get the hint and ask for a date or your number and if he doesn't he simply wasn't that bothered in the first place.
I have to think 4 emails isn't quite enough, yes some men do ask for your number fairly early on in the email exchange however others do take longer.
I had a guy on tinder who lives 2 miles from me, good looking, seemed nice was quick to respond, gave compliments etc, but after about 12+ exchanged tinder messages still hasn't asked for my number I kind of didn't reply to his last message. Maybe I should have offered mine, but I'm a bit old fashioned and like the man to ask first.
The rules also suggests waiting 3 months I think (could be wrong here) before sleeping with someone, maybe I'm a bit easy but 3 months seems like a long time, I usually do 4-5 dates but I've also been known to sleep with someone on date 2/3 if it felt right 
Also read why men love bitches years ago, this is pretty good and I have to say it's the better out of the two books. Both good reads but I found why men love bitches to be the more realistic one.
