Okay guys I just want to write a little review/summary about POF.
I am not going to be bias or vague but I am going to share my experience on this community.

Plenty Of Fish, a site much like our other online dating personals, is probably the largest free dating site in the English-speaking world, with the site even being offered in several other languages as well.
So first up is Plenty of Fish, one of the more popular dating sites and by 'popular' I mean that it's free, there is no vetting process and it's like looking through 700,000 profiles from people who would quite happily set you on fire. Anyway, one of those many, many free sites is Ok Cupid. The Ladies 'Don't message me, I don't want to talk to you. 'My favourite word in the English language is "meadow" - aw, mine is 'cunt.'...
On the male side you have highly original taglines, for example: 'Looking to meat someone.' (sinister) 'Who's out there! ) 'Left prison for good' (Stayed in prison for evil? Looks wise this isn't too bad and a million times better than that abomination from hell, Plenty of Fish.
I don't remember where I heard of POF but it's probably from a website somewhere.
