Jon Bartlett, a most interesting reason to use your own name!
Tootler, I love the idea that you think the other Tootler was you but can't be sure.
I have used the same Mudcat name since joining several years ago, and rather like the idea that when I post, people read what I have said then and there, uncolored by ideas of age, place, gender, or musical credentials except what is in the post or what they know of me from other posts. There are a number of folks who tend to be on the same threads I am and we have gotten to know each other fairly well online; some of these I have met; I have met a number of Mudcatters in person. Sometimes I will be talking to someone that I know in 'real life' as well as online and know both their names, but they are surprised to find I am 'celtaddict' and that always gives me a laugh for some reason. I have given my 'live' name to a number of 'Cat friends of course, but still rather like the relative anonymity of a pseudonym. If I disagree in a civil discussion, I can disagree civilly, and if a thread descends to insults, I am out of there.    I may disagree with someone but don't get into arguments or 'shots across the bow' because life is just too short.
