first of all, you can't do it, but I can - and I think Joe (MCJ) can as well, not certain.
The idea here has always been that you could choose to be anonymous - or not. After giving it some thought, I have decided that it's only fair that if you really want to change your name - not for reasons like "I don't want to be associated with my former self" (or comments), then - I'll honor the request.
Your name can be just about anything here - like mine, with an embedded space in it. It can be a 'handle' or pseudonym ("pen name", I suppose), real name, something in between or just whatever.
I will post a "MAP" of usernames changed, simply because it's not intended to 'fool' anyone, it's only an accommodation to users who have changed their mind since signup.
Now, the real "how to": send me a PM with your desired "new" name, spelled with punctuation as desired, etc - and I'll 'fix' it, send you a note by email when it's done, and then all your posts will change to the new name and you will have to (reread that - "HAVE TO"!) use the new name to log in here. Once it's done, it can be 'undone', of course - it's just an attribute of your user account # here, frankly. I will NOT allow names with "UC", "UC_", "MOD" or similar that might confuse someone here any more, but if you've already done so (I can think of one - no big deal), you're fine!
I understand that there might be several people that want to do this, so - just try to be reasonable and keep it to a minimum unless you really want to change it permanently. Because of this being somewhat confusing for people who have grown used to your existing name, not only will I post a "Map" (OldName = "ImATurkey"; NewName = "Not Really", etc - I will not allow it to be done more than once, perhaps with the exception of reverting if you decide it wasn't a good idea, but PLEASE - don't make frivolous requests! I have better things to do, but I want everybody to "have it their way", and I always want to be flexible as we possibly can here!
<===<< The "PM" button is right over there, slightly to the left of directly under my Danish flag. If you have account login problems, 'firstname.lastname@example.org
' is the alternative way to get my attention.
BY THE WAY: it was brought to my attention that IF you are using the default layout for cell phones (called "WAP" for Wireless Access Protocol) it won't look like what I see right now at all. To understand what I mean, pick the "FULL VERSION" button near the top left corner (right under the dual "UNITED CARDISTS") of your current display to see things normally. You can go back to the small device mode using a button on the bottom (as I remember) once you see what I mean. It says "Mobile version" - green link right above the "Site Lock" security shield emblem. It's also available on the top right of the standard view and looks like a small cell phone right under the "Search" box.
ALSO POINTED OUT: I won't change it to something in poor taste, like "Mister Baitor" (or worse). Keep it in good humor, folks!
