The IETF85 Meeting agenda web page - https://datatracker.ietf.org/meeting/85/agenda.html - has links to "agenda" web pages for each working group. E.g., for "avtcore", there is a link to: https://datatracker.ietf.org/meeting/85/agenda/avtcore/ However, each working group also has a second "agenda" web page, at http://tools.ietf.org/wg/<wg-name>/agenda . For example, for "avtcore", this page is: http://tools.ietf.org/wg/avtcore/agenda This second web page is usually more comprehensive than the first. E.g., the second web page often contains links to slides, whereas the first does not. Why are there two different "agenda" web pages? Why not have only the "tools.ietf.org" web pages, and have the main agenda web page link to those pages instead? Ross.
