Hi eric, Just a friendly suggestion here; feel free to honor or ignore as you wish:
When posting a columned chart, as you have done, particularly one with many columns, just pasting it into an e-mail client is usually going to produce something *extremely* difficult for other people to read -- something like you see below. Most people use some limit of line length, your own mail client may be wrapping to some set length on send. Other people have clients that will wrap it upon receipt. (An old standard that is often ignored these days is 69 characters for a line wrap.) I suggest taking a screen shot and posting it as an attachment. At least, I'd be much more inclined to try and decipher it then, since the columns would all be lined up correctly, even the lines. Others may say 'No,' because they don't receive e-mail, and thus don't see attachments. I cannot imagine why anyone would *not* want to receive list mail directly, but to each his or her own.
