   Okay, I understand that.

   The existence of numerous variables still unnamed even after ten years
of the discovery seems to me to tell that this process is not working
ideally.  As reported in [vsnet-newvar 686], some of such variables have
been independently discovered by other observers (the identification
was incidentally found by me).  The combination of such observations
would provide additional information about the variablility nature of
the object, but in the absence of publicly available full list (the quoted
positions on the TA website are not often very accurate, which may hinder
secure identifications without associated charts), one would have no idea
how many other identifications have escaped detection (quite a loss...).

   I am not personally specially interested in the details of the TA
discoveries, but if there is a publicly available (i.e. on your web) handy
and comprehensive list of TA variables, enabling modern-day identifications,
I would be fully satisfied with that.  Perhaps this requirement would
apply to other variable star observers and researchers.
