I'm looking for a term or terms--neologisms--meaning roughly "handle" (not "password"), as one's given or nickname in the author or topic column of an index.

Eg, I have two of them, Dale Hileman and dalehileman. David of WW has at least four, including Wizard of Oz and the abbreviations WoZ and Wiz. One has to know the difference between one version and another because the website algorithm treats them differently and each serves a different function in the overall scheme of things

Just as it is important to distinguish between contributions called a thread, a reply, or a followup, one might suppose each kind of "handle" would also have a different name

Thanks for all present and past help in straightening out such terminology--
