After this long time, where the group has grown well, I was thinking about some contest:
The first contest is about nominating a Picture out of this group, which will be feautered then on the main page for a month with the Link to the owner. After this Month we all will nominate a new Picture. For this I also will make a folder for all nominated Pictures.
The second contest is about finding a Picture for the group avatar. It will stay there not only for a month, perhaps even for one, two or more years.
For both contest you have to be a Member.
Two years after founding Animal-World, the Gallery is now full of Animal-Pictures of different kinds. At first, it was only allowed to submit one Image per day, now we've chaged it. You can submit now 5 Images per day, per folder. I'm guessing so the group is growing a little bit faster, than when it is only allows one per day.
If there is a folder needed for a kind of animal, which has not yet an own folder, just write a massage.
