regarding adaptions/sequels to "Season's Greedings", these stories came to my mind:
above mentioned
Momentum by Kathy Brown and
Let it snow by Alicia U.;
Sugar and Spice by Labrat, a favourite of mine (this is the link for the PG version)
by Annie M
An LnC Christmas Carol , a lovely and waffy fic;
a waffy round robin fanfic:
Season\'s Wishes ;
two lovely vignettes by Wendy Richards:
Season\'s Regrets and
Season\'s Greedings to One and All ;
another one, dealing with Lois' cynical attitude about Christmas, is
Lois Lane and Magic of Christmas by Chris Carr;
finally, a sweet and funny series by Phil Atcliffe, starting with
The Spirit of... but probably there are many others!
