@melee09 Flip a coin? Heads is one, tails is two? Write one and two on slips of paper and have someone draw them out of a bowl? Close your eyes and eenie meenie minie mo it? It's cool - it's not like this is the Grammys or summat. :)
@katsamste The tag challenge is a competition that runs periodically on the home page. The object of the challenge is to choose two "tags" at random and put them together in one picture. Tags are ways of identifying your shots by subject. For example, let's say you take an adorable picture of your cat "Mittens". You post it, give it a title and then think, "People who love cats would love this picture!" While you're uploading you could add the word "cat" to the tag section of your photo and then if someone wants to look at cat pictures they would be able to see Mittens' lovely picture by clicking on the tag "cat" on the "search by tag" page under the Browse section. To choose tags for the challenge, you go to the "search by tag" page run your cursor over the tags and land on one, then another at random and that becomes your challenge. Sometimes you get two things that make complete sense, and sometimes you get two very different things. The challenge is run by whoever won the last tag challenge. That person picks their top 5 favorites and the rest of us get to vote in the winner of those 5. You don't have to enter the challenge to vote, but it's fun if you like putting random or off the wall things together. I hope that covers what you were looking for- sometimes when you're typing these things out they make sense to you, but not necessarily the people who have to read it!
hahaha, nice try @gurry ! wouldn't that be nice? ;)
