eap Mailing List: RE: Issue 180: SA Descriptions

[McCann, Stephen (stephen.mccann]

Dorothy, Bernard,
        Indeed, perhaps the use of WPA within the description should
be avoided, as I understand it to be a WiFi Alliance TM.

I also agree with Dorothy, in that this is a very informative description
and very welcome to people (like myself) who are sometimes 'on the
edge' of these detailed discussions. Thanks.

Kind regards

Stephen
