I noticed that it's been a while since the last theme was implemented. I think the concept of a community wide concept for photography would be wonderful and bring us together even more.
There were unofficial themes organized by Dimitrios if I am not wrong, but would be nice to implement a new theme. So far official themes have been work and water, unofficial themes that I remember have been self-portrait, graffitis and another one I don't remember. Would be nice to do some theme that no only involve people of the community but makes you interact with people you don't know. One that I kinda enjoyed from JPG magazine is the Stranger theme, not only you have to get a photo from someone you don't know but you have to get a story or something this person said and the person name.
