Bruce,

Personally, I like make two challenges distincts. Although science et technologie, I  not had the time to put my photo LOL....
I think  these challenges are a motivation for all member for participat in the forum. And you know, the motivation is a very good element ...

Now, explain me your idea for to join this two, for example in August: "science and technology" and perspective??? I believe this would be too complicated by someone

It is my point of view...
