Secondly, I'd like to note that some of those names I know all too well.
Elfy has been busy with school, work and her own site; though I believe she does on occasion pop in to have a look.
Wolfwood, I believe is still quite active though I'm afraid I was forced to kill SotM.
Tenchi's already had his mention (YOU CAN IM ME TOO YOU KNOW!!)
Kurumirina tries to pop on when he can, but the last time I spoke to him, he was attending university (I could be wrong as I tend to confuse people I don't speak to on a regular basis)
Terran has had issues with regular internet access. I miss talking to him on a daily basis.
as for the others...can't say I talked to many of them other than Aifa. And I only see him on MSN occasionally
