Well you're not the only one. I also did it myself and I'm the one who put it there

Maybe I should make it more obvious. I'm redesigning the front page at the minute so I'll have a look at that.
The members login is for buyers to register after which they will gain access to unlimited lightboxes, although photographers may find this feature useful too.
You could create lightboxes and email them to anyone you like.
It has a separate registration so I can keep track of contributors and buyers in a different list.
Regards
John
