I shall now bring common sense to this topic.
06 users is the answer.
Why? i hear you cry. well...
01 users stopped coming mainly.
02 users stopped coming mainly.
03 users stopped coming mainly.
04 users a few left.
05 users quite alot left but a few leaving
06 users alot because they have only been here between 2 and 14 months. Thereofre they are not bored yet and are staying.
07 users only just 07, so not many joined.
END OF POINTLESS, MOST PROBABLY WRONG ASSUMPTIONS.
