I did think about changing my Mudcat name after getting to know one or two other members in 3D. The initial decision to use a "handle" was based on the fact that most others here don't post under their own names and, having no experience of using other discussion forums, I wasn't sure what I was letting myself in for.
After a couple of years of visiting this site, sending and receiving PMs, etc, I have no problem with using my real name, Merrick Hamilton, (mother had a great sense of humour), but equally find that the Mudcat handles work just as well and I don't feel that I know someone less well just because they haven't told me their name.
There are some regulars here who could be picked out by the content and style of their postings under any handle.
C-flat.
