Thank you for the useful piece of advice. I promise to try harder. (02)
Thank you for the continuous contribution to the [ontolog-forum] list. (04)
May I suggest the following, so your posts could make it to the
community and the archives in a form that may better serve our goal of
building a dynamic knowledge repository together. (05)
ref. http://ontolog.cim3.net/forum/ontolog-forum/2010-09/threads.html (06)
1. please use "Reply" to a message to preserve the message thread (as
that would allow our archival system to thread the messages properly.) (07)
2. please preserve some header/reference information of the previous
message that you are citing. (08)
3. please use plain text in your posts (rather than "rich text"), and
leave a blank line between paragraphs and listed items. ... This will
allow the "PurpleNumbers" (ref.
http://ontolog.cim3.net/cgi-bin/wiki.pl?PurpleNumbers) to be populated
by our system. (09)
4. please observe community suggested self-regulatory guidelines (and
help keep the traffic volume of the list sane.) (010)
Thanks & regards. =ppy
