Also some of the people who have posted to this forum, their links aren't working.
Most of this is driven by the nodeaccess module and also some custom code.
The templates have HTML5 and CSS coding which makes them super flexible. The multiple homepages also provided added degrees of flexibility.
There are header images to showcase promotional offers or special events.
I wanted to state that i just found and joined this group and am planning on getting a awesome drupal dating website out in the web.
Found a couple of topics on forums and the web about dating websites build upon drupal but 98% returned a 404, so no inspiration from there.
