List Policy
(Revised 2014-09-03):
The subject of this moderated mailing list is category theory.
Items on another subject may be posted if judged by the moderator
to be of interest to subscribers. Discussion
of such posts is excluded.
The list is to be used for concise discussion that is suitable for email distribution.
Posts are not transmitted if, in the moderator's judgement, they are unsuitable.
Postings to the categories list will be courteous and respectful.
Expression of disagreement must be polite. A submission judged by the moderator to be
offensive or defamatory will not be posted.
Submissions judged to be related such material
will not be posted.
The categories mailing list distributes only text messages.
Do not send attachments, messages containing html or excessively long postings (longer than about
10K).
The default setting for some email clients is to compose messages
containing html. This setting is easy to
change. Postings with attachments or with html
will be discarded.
Help with avoiding html is

There is an archive of postings at
nntp://news.gmane.org/gmane.science.mathematics.categories
maintained by Gmane. You may need a news-reader client to access it.
A subject-sorted list of postings June 1994-December 1999 is at
www.mta.ca/~cat-dist/catlist/
This was initiated by
Karel Stokkermans of the University of Linz
who maintained the list
from June 1994 to November 1999.
The full archives of postings on
categories
until 2009 (when Outlook made this impossible) are at

The postings are filed in yearly folders called 2006, 2005 etc.
Within those folders there are monthly files.
A list including email aliases for many subscribers to this list, among others, is the structures directory maintained by Vaughan Pratt.
The following have information on regular seminars in Category Theory.
