Case study: A dating site made in Drupal

The dedicated section of Drupal is http://groups.drupal.org/dating. However, the details of exactly how a dating site is built (what modules are implemeting what functionalities) are not given. People seem to avoid that and and couldn't figure out why.
I hope in the future people will be more willing and feel more comfortable to share their details.
Until then, a showcase maybe would be appreciated in the dedicated section of drupal site (i.e. here) as I have seen no similar showcase so far (a dating website built in Drupal) in any section of drupal.org (check this statement by searching after "dating"). So, I thought maybe this is a good opportunity to bring the basic functionalities of a dating site in the front of Drupal community and see how they can be implemented to the more extensive details.
This is the reasoning behind my wish to post here the details of building my dating site (as a showcase).
Although the site is not yet finished, I hope - in the spirit of the open source that has been always the basis and represents the premises which the drupal website itself has been built upon - to be allowed to display this unfinished showcase and allow for interested contributors / members to bring valuable contributions. However, this is not a project of defining a module, a theme or a code snippet. As the entire dating site that has been built so far is based upon drupal modules (very few code snippets) I see this showcase as a display of details (modules, themes, etc) that I use to implement the functionalities required.
The aim is to finalise a complete showcase that every interested person that arrives here can use it to implement its own dating website.
As I am first time here, I do not know the rules to post a showcase, but I do my best to learn.
I thought that, as a common sense, in order to avoid being accused as promoting my site, I have decided to not display the web address, unless somebody from Drupal webmasters group let me know that I am allowed to do it.
Since then, I think maybe it is usefull to list the modules I have installed so far in my dating site and then trying to provide details of basic functionalities of a typical dating website.
So, let's start with
1. Basic functionalities of my dating website / showcase
1.1. Premium member may access the emails of other members (upon TOS - Terms Of Service) .
1.2. Chat (not available for trial members)
1.3. Can see the member status (premium, new, activity, last logon) (not available for trial members)
1.4. Premium member may see the private photos of other members (and possible their private videos)
1.5. Can block other members to initiate chats or to receive emails from them (can block such contact initiatives from all members that are based in a country or another, as selected by user - or many countries)
1.6. Advanced search (smoker / non-smoker, etc) - available to premium members only
1.7. Messages with / without virtual gifts (this is optional - maybe in version 2.0)
1.8. Sending a smile to a member (only by clicking a link - not by sending a message with a smile attached)
1.9. History of all connections (to whom there were sent a message, a chat initiative, a smile, etc)
1.10 Who's on line (disabled upon administrator's decision - for starting sites maybe that do not have alot of customers at the beginning of operations, but needed later on when the site has grown enough)
1.11 Bookmarking a favorite member (I admire him/her) or receiveing a bookmark from admirers (they like/admire me)
