Hello Herb and Ross,

Thank you both for explaining how to use \usepackage{xspace} properly.

Not in the habit of using the above, so I checked them out. \C \O \P and \S are useful (to me), and even if they were not, I would not redefine them (\renewcommand) for personal use. As to the others, \B \T and \U generate Undefined control sequence'' error messages. \H seems to do strange' things!!!

I believe it!

Not so sure about the above! My practice has been:

Whenever I want to introduce a personal command via \newcommand, I enter the details in the preface and then do a typeset. If there are any complaints, such as the "already defined'' one, then I back off and revise the my command's name. So far that has not caused problems, or, at least, I'm not aware of any problems --- yet!  :-)

As to collaborating with other authors, I'm not in that ball park yet, but I've often thought about how user-defined devices would be handled. Methinks a great deal of discussion would be required. For a team effort, a good approach  might be to eliminate personal quirks, but I suspect that could be contentious.

However, Ross's use of the adjective 'foreign' puzzles me. How come you (Ross) did not write: "... with any author.''? As to bibliographies, I'm not into the BibTeX league yet, and have found \begin{thebibliography} and \bibitem serve me well --- so far.

Not very keen on that solution, but I will keep it in mind. ;-) Pleased to know that \C and \O can be used.

I can see the usefulness of \AA but I've often wondered why \LaTeX bothers with \SS.

Advice from Herb and Ross always helps. Thanks!  :-)
