That address has not worked for many years past.

Neither the fr.autres.* subhierarchy nor the group fr.autres can exist at  
all without the agreement of the administrators of fr.*, so I see no  
problem in agreeing with the fr.* administrator to handle the rare cases  
in which fr.autres needs some amendment. Too much copmplication in the  
chackgroups rules. So I do not want to change it (if any other USEPRO  
member wants it changed, then he will have to speak up).

Yes, I was aware of the similar cn.bbs.* case.

Yes, I agree that any number expressed in 32 bit would be better. Can Russ  
quietly slip it in?
