[Retros] Thema Danicum

[Henrik Juel]

Here are solutions and original retros from recent issues of Thema 
Danicum.

But first a somewhat sad announcement: Thema Danicum will stop bringing 
originals after 2006 and cease publication after 2007 (during 2007 
things will be finalized with solutions, awards, and articles). Since we 
have enough originals on hand, we will not be able to accept any new 
originals.

I want to thank the many retro composers who have submitted fine 
problems during my tenure as retro sub-editor. Maybe we can continue the 
cooperation some time in the future.
