Have you heard of notpron?

[DanyTNT]

notpron is a riddle "game" which is played on a website. You are basically given a picture and you need to somehow solve the riddle embedded in the picture. It is very cool and I along with some friends managed to get to level 46 (though it took us around 7 months). The riddles there are very hard and not straightforward and many times require technical knowledge. If you are that type of guy (or girl), so take a look and maybe you'll overtake us

PS, please don't delete this thread, I know it has "pron" in its title but it is totally safe for work.

I hadn't until now, but I hate jumping through hoops in games, so I'm not going to bother figuring out how to get to level 5.

Edit: I've actually gotten there and it wasn't too much of a stretch, but I'm definately quitting now, while I'm still "ahead".
