Hello all, I'm enjoying this burst of excellent information on this list - have we reached critical mass? However, I think I'm having a problem with my e-mail server. They're shutting down tonight for repairs, so it should right itself, but as is, I'm getting snippets of a really neat series of discussions. There are answers to apparently unasked questions appearing...easy to follow but I can't help but feel I've missed interesting things. Does our list have an archive for cases like this, or for past explorations? Gary (Montreal)
