Re: periodic hexadecimal reminder

[thinkit8@lycos.com]

rafsi for the hexadecimal numbers have already been proposed and are 
in the wiki.  despite infighting, most agree that rafsi are needed.  
as for specifying bases, that would be a complete waste of a cmavo.  
since hexadecimal is default (unless overridden by an irrational 
adherence to tradition), it's easy.  decimal is ju'u dau, and the 
default is ju'u pano, or something like ju'u no'o.
