SUBMITTING COMMENTS

[zak seidov]

Dear Neil, seqfans,

Why not to set up the rule, 
that anyone sending any comments/extensions/editing
etc. SHOULD CC it to all involved ones, 
at least to authors.

[[[As I said many times only Bob does it regularly
(at least he always sends his %C to me)
and I'm always very much grateful to him.]]]

Sometimes VERY INTERESTING moments 
are missing authors
because as I said many times
EDITING is MORE INPORTANT than 
SUBMITTING NEW CONTRIVED SEQUENCES.

All the great editing job done 
mainly by Neil but also by co=editors/commentators 
are simply left unknown to other SFs.

Thanks, Zak
