No it's not really eletist, it is what is known as "good forum houskeeping".
Over a period of time the server bogs down with so many "inactive" members, and you need to do some spring cleaning to free things up again.
Also a lot of "surfers" come onto a forum with no real intention of staying and sign on with multiple names just to be of nuisance value, then "leave the building" leaving their legacy like graffitti vandals.
So occasionally a purge needs to be done to put the house back in order. In our case because Dave has been busy, it probably hasn't been done in a while.
So, as Janet said, occasionally pop up and comment on someone's flower or what ever, and you cover your ass.
I have no problems with it.
