If you state exactly what you need, then I am sure that a developer will respond to this thread.
So in other words: what does a dating addon need to do for you?
Do you want a tiled memberlist, with widgets?
If yes, then what do you want to display on a tile and on hover? (sex, age, location, registration date, etc)
Do you need dating specific profile fields?
Do you need profile widgets related to dating?
Do you need profile field search?
Do you need a function for users to define what kind of date they are looking for? Should this be displayed on profiles?
Do you need a function to show 'your matches' to the user?
Do you need a dating entrance portal like the more popular dating sites have.
Do you need a function to send interests (similar to friends)?
Do you need paid membership and related usergroup benefits? If yes, which?
etc.
