The option "Fixed attributes = ..." will do the job.

Actually this is a good idea. After thinking a while, I wonder if anybody at 
all would like not to preserve the preset values. So if nobody complains, I 
will set the behaviour such that elog always preserves the entries if one 
edits an existing message.

Sorry, I haven't fully documented it yet, will do on Monday next week. For 
now, see the configuration file for this forum which is attached.

That's strange. This error should only occur if someone uses a user name or 
password with more than 256 characters, which I hope is not the case. Have 
you tried changing your password etc. in this forum? It also runs 2.1.0 on 
Linux.

I made a version under 

http://midas/cgi-bin/cvsweb/~checkout~/elog/elogd.c?rev=2.67&content-
type=text/plain

which has improved error output for this problem, maybe this helps.

You run two instances of the elogd daemon like:

elogd -p 8082 -c /usr/local/elog/elogd1.cfg
elogd -p 8083 -c /usr/local/elog/elogd2.cfg

No, not yet. I put it on the wishlist. I'm looking for a C function which can 
doe lexical evaluations like

  author="stefan ritt" AND (category=Question OR category="Bug Fix")

does anybody know such a function?

This operation is done via Java Script, which has to be enabled in the 
browser. If anybody knows a better way, please let me know.
