From: "James O. Whitlock" To: Subject: Re: Please Join the Commons/Megaconference Load Tests Date: Wednesday, July 18, 2001 1:47 PM Bob, I hope you will keep privacy interests of healthcare sites (and others too re publicizing IP addresses, email addresses and the like -- at their option and in their style) and the likelihood of regional sub-hosts (such as our own Western New York group's efforts last year -- unknown what this year's participation interests will be) in mind as you finalize plans for this year's MC event. I look forward to seeing it unfold. Don't be surprised if we're more quiet than last year at first; I expect to be back on a Maine Island with my young daughter soon again until the Fall semester begins. I now have a few more local colleagues who can help out a bit, however, and will maintain some email, if not IP-video connectivity, but we probably won't have a clear picture of institutional involvement until a bit later this year.
