Luis - I think that being a screener here is less funny than some of us might think. Imagine 100s of new pics every day to "screen" (=download) - means expenses, explanations, responsibility, and for sure lots of time. Why not giving them a little freedom, lets say for recreational purpose.
I haven't seen any superficial or high-handed, or what some feared, selfish or stuck-up posts so far. They do their job, they do it voluntary and I for one would even wish they could ADD pictures to the database. Because they do it well.
What's left for Johan to approve is pretty sure also worth enough (at least it can't hurt) to be shown to the public.
I like the Screeners! Did I tell you they never rejected a pic of mine?
