It's looking like a good idea to me:
1. It would multiply the number of T-girl reviews, because it would become the main UK resource and snowball effect - good for the site, good for punters who want to do research
2. It would clearly be a T-girl section and no need for those who aren't interested to accidentally read something that offends them
I can see the idea also applying to other areas, such as dominatrixes, BBWs, MMF meets etc, but each would need their own section, because part of it is the SEO / snowball effect of attracting reviewers.
Maybe some of the other areas wouldn't justify their own section in the same way though, e.g. a girl offering MMF would also offer standard punts whereas a T-girl doesn't also offer genetic girl punts.
