I was on dial up until just about four months ago.The Coco list was never a
problem with me, it's the web that was killing me.
The Weather channel and doppler radar, in motion, would take MINUTES to
load. Now it's only a few seconds.
Right now, I'm waiting for approval for the listings, which will be sent in
seperate emails, from the administrator as he finds my email and time to
For now, I'm going to experiment on formatting of these so they are legible

Meanwhile, I'm working on an idea that may work. I should know something in
a few hours, depending on how much I build up my stock pile of aluminum
sheet. More sheets mean less productivity. It takes more brain power to
collect those aluminum sheets than it does to develop the coco, I think..
er, the best I think I can think, as it goes ahead.
