PerfectParents.co.uk provides single parents with a place to meet online for friendship or romance. The site was launched in 2008, and though not very busy in terms of membership levels, it does have a reasonable number of good quality profiles. Most are from United Kingdom.
PerfectParents.co.uk offers all of the standard features you'd expect. The only drawback is the low number of members. Finding people nearby can be tricky, especially if you don't live in a populated area. The search tool lets you specify a county, as well religion, and smoking habits. It's also possible to show only people who've been active within the last 24-hours.
The only communication that's open to free members is sending ice-breakers (winking). Emails, sending gifts and reading another person's online diary all require upgrading to one of the paid plans. These start at £14.95 for one month, though discounts can be obtained when subscribing for longer periods.
Other features offered by the site include a personality profile (not available to free members), horoscopes, and a romantic profile report. Once a personality profile has been completed, it's possible to view “recommended matches”. These are members who've been automatically selected as being compatible with you.
I did find the lack of action here a bit of a disappointment. If you're looking for more life I'd suggest either Singleparentlove.com or even just plain old Match.com.
