Sorry LyraSilvertongue I do think you are a little bit unreasonable here.
There are so many names already taken when you sign up to mn, and maybe her name means something to her (If I was to guess I'd say she was born in 1975, but no idea about the Lyra bit).
Her name isn't very like yours compared to other similar names on here. I am pot of tea (because I think tea should be made in a pot, never in a cup, yes bizarre I know), but I know there is a cup of tea or somesuch on here too, and the name teapot was already taken when I signed up a few years ago.
Probably a lot of names are taken but the person hasn't posted her in years, so maybe a recycling system where posters who haven't signed in in 2 years or so have the name made available again to new posters.
