Arrived (epylar).  New player.  I start at 1419/11/26 (rule 2.3).  The quorum as of before my join was 6 (front page), and the influence of the 6th highest member (TAE) was 10, so my starting influence is 10 (2.6).

However, I must be added to the sidebar before any of this can be validated/I can do things.

CORRECTION: My starting influence is the median of the influences as of the join real world time. (Interestingly, it would seem that this would not change the median—i.e. 1 2 3 would become 1 2 2 3, 1 2 4 5 (median 3) would become 1 2 3 4 5 (median 3), 1 would become 1 1, etc.
