Since 2011, to answer the question.
I have seen many incarnations of some members for whatever reason , not necessarily devious, and have sometimes had to adjust my "mental picture"
Elegran remains "elegant", I confuse my absents and activists, glamma makes me think ofMolly Weir in her heyday (or Joanna Lumley) marmight makes me wonder "just what she might do", I remember ethel etc when she was prickly, and am not able to type rosesarered without having that dreadful song in my head for the rest of the day!
It has sometimes taken a wee while to spot a new incarnation and sometimes it is all too obvious, but that really doesn't matter, you are who you are on GN !
At meet ups it has been odd , difficult even, to use "real" names.
