Note from moderator

Based on the the desire to allow discussion to flow freely, I have recently posted several messages which do not obviously qualify as discussion of category theory. Without criticizing either the posters or myself (for letting these posts go out), I will query (but not censor) future posts which are not clearly related to category theory. It should be noted that general discussion of aspects of (La)TeX or other programs which are widely useful in the community are clearly related to category theory.
