Hi Richard...
You made a very nice puzzle! First of all the puzzle itself is brilliant, even more brilliant is the fact you used 25 names which refer to the puzzlers on this site
Though this weekend some puzzlers have other things in mind (lots of them are in Giessen...
)... I think all of them should solve this puzzle 
But maybe some of them (like me) need a little hint to start things up... could you give some little hints?
I like this puzzle... if Berni agrees, could you make more of these?
Greetz,
Arvid
P.S. What is the reward if you are the "25th puzzler" who's name isn't used in the puzzle?
