Sometimes I wonder Mate if some the lurkers (that are many) think that we are a small self-sufficient group, who does not want more participants. If so, we should once in a while (like we have done in the past) make it known that we would love new people to come and play. I'd love to have more people, competitive personalities or just some who like to rev their brains. It did a lot of good when HappyPass came, and it would just be very good to have some like him every month.
Staying with silhouettes and not going (back) to pictures works fine, as they are not that easy to crack just with technology.
Edit: Some people may be shy because our way of bantering, but when I compare all three challenge threads in AH&N with many more around, we are the bunch respecting our fellow PPRuNers, all without exception.
