>Actually there are only 337 (the last time I checked) people with on-line pictures. Of those, you had to login within the last 20 days and be associated with a company (so Independents without a self company are also excluded). So the odds really arent't that bad for you to get up there.

So, I may hope? :) BTW, have you already been the Member of the day? I don't remember...

So, the probability may be calcualted as: (right?) in each particular day for each such person:
prob=1/337+1/336, if all these people had access in the last 20 days in each day.

Let's count for simplicity 2/200 or 1/100.

This feature started from Feb. 19th, say, 20 days.
How will be prob calculated in this case? I never studied theory of probability seriously :(
