When i was initially trained it was with the use of the C/caps. The use was to signify respect, and actually i have done it so long it is more of a habit now then anything. I see a capped name and i will cap it, the assuption being that they must prefer the cap to be there or they, themselves, wouldn't have put the cap there. If someone tells me the caps aren't important i will attempt to remember that, but no promises!
I also believe though that respect is earned. And that everyone deserves my respect until they prove otherwise, which sometimes doesn't take but a few moments. (When i stop capping is when that person had pretty well lost my respect.)
To me the caps aren't as much an overall issue as subs who call every Dom/me they meet Sir, Ma'am, etc. THAT title is what has to be earned imho.
i can type it either way, although the fact word auto caps "I" when i don't for a business letter is helpful!
Thanks for all of the thoughts on the topic!
