MCI Telecommunications Corporation Consumer Relations Consumer Markets 1200 South Hayes Street Arlington, Virginia 22202 (703) 425-6000 November 13, 1991 In response to the piece posted by Brian R. Krause on your [inter]national bulletin board, RISKS Forum, titled "MCI Friends & Family & anyone else with a touch-tone phone" on October 23, 1991, MCI wishes to post the following information. MCI is aware and sensitive to privacy concerns of its Friends & Family customers. Additionally, MCI is aware of the isolated incident where its Friends & Family voice response unit (VRU) Update Line was abused. MCI has made — effective November 7 — the access more private by altering the VRU access procedures. In order to acquire information about a Friends & Family Calling Circle, customers have two options depending on the information they want. Option 1: Enter the last three digits of your MCI account number to receive the status of all Calling Circle members. Option 2: Enter an individual Circle member's 10-digit phone number to learn the status of that individual. We hope this explanation addresses any concerns that may have arisen as a result of the "RISKS" posting. Karen Heyison, Manager, Consumer Relations
Yesterday's sudden fall in the stock market brought to light a serious Achilles heel in the way our country's economy is growing. As panic hit more and more traders, the faint clatter of computer keyboards added to the fray -- virtual stocks were being virtually sold at an amazing pace. It was less of a concern in the 1989 crash, but now we should be even more aware of the effect computer-assisted trading can have on the market. Inside of ten minutes, millions of shares can be unloaded very quietly. The securities industry can only grow faster in the coming years; if it doesn't build some cushions to avoid massive "anonymous" selling, it may be in for an even more serious down-turn.

In their stock statistics sections, Prodigy has a 14-character maximum length for the company name. Apparently, they just chop off any remaining characters. This morning, I was surprised to see the following stock among the ten listed under yesterdays "NYSE Biggest Percent Gainers": STOCK LAST CHANGE PCT CHG ELECTRONIC ASS 2 3/8 + 1/4 11.76 (I think this is supposed to be Electronic Associates, ticker EA).

I've completely lost track of what's going on with the gray vs. gorman "discussion". I hope you'll put something in the next Risks saying that further communications on the issue will be conducted through the lawyers of the parties involved or something to that effect, something that leaves RISKS out of it! P.S. I'm sure this is an example of the risk of computer communication — most people would post things they wouldn't say to another person standing next to them.
I greatly appreciated all the supporting mail I received on this topic. I try very hard to keep RISKS consistent with the self-imposed standards of being OBJECTIVE, INTERESTING, PROVOCATIVE, THOUGHTFUL, in GOOD TASTE, and, above all, INFORMATIVE. I certainly learned something from both antagonists, and about them. Whether or not that was RISKS-RELEVANT or not, I believe that once something unfortunate has slipped through, it becomes necessary to set the record straight. But in keeping with the current efforts to raise the standards (again) in the continuing epicyclicity of RISKS, there are likely to be fewer mundanities for a while. Thanks again to all of you for your continuing contributions, including those that do NOT get included. Sorry, I cannot respond to everything. So, if you think I missed a GOOD ONE, PLEASE poke me; I probably did miss it, especially if the Subject: line was nonspecific. PGN]
