Hello Andrew :-)

IMHO there are still two main problems with Dolphin to build a dating site...
First is the separation by gender/sexuality. For example men hetero have to see/attain only women hetero profiles, men gay only other men gay profiles, etc...
The second is that there is still no email addresses filter. Such addresses, as well as other contact information like phone numbers, still can be posted in many places.

Photos management, that is a main and quite basic feature, has to be see more improved/simplified too both for admin and users. It will be much more simple to use if this could be some icons under each photo thumbnail to edit/delete/move it to another album...
