I think one must not lose sight of the fact that, even on mainframes, disk space is inexpensive. I've received a few price lists for the L-Soft off-the-shelf business and it seems the market price for "second class" disk space (meaning units not running off the latest whiz-bang non-volatile write-through asynchronous migration cache controller and with a slightly lower transfer rate, which are perfectly adequate for storing list archives) is on the order of a few dollars per megabyte per month. Most of these price lists are for "external" use with a very definite profit. The price for on-campus use, which generally corresponds to actual costs with a small margin, is more like $1/meg/month. Well, it takes a lot of notebook editing before you save a megabyte, and then you've just saved $12 a year. So unless you have a high volume list or people post long messages, it's just not worth your time. Eric
