.... or maybe he meant to say that all our personal information ( friends, what we like and do not like, gender; l ocation ; contact informatios as email , Skype , telephone number , etc. . ) will be visible ONLY to members who are added as friends and not to others.
Yes, it is an old site made in 2005/2006 from a german professional using THIS free CMS.
At that time was sure something terrific, but we can still have some idea form it, for example would be nice if the next galley could: ...have the possibility to choice between a light (as now) or a dark background (many professional prefer to have a dark background). Of course we can do this by skin, but if just "out of the box" of gallery 6 it will much better;
...have different photo album for the same member, each of them show a single photo in the member index, A user can, for example, have a photo album for "Vacation in Namibia 2011", another for "Vacation at Oslo 2012" and so on,
...have the possibility to sell space to members (as Flickr does)
