AW: [ RadSafe ] European Union (EU) Drinking Water Limit forTritium

Wed May 23 08:19:34 CDT 2007

Franz is not "persona non gratis" on Radsafe; if he was, we would not be 
seeing his posts at all.  Franz is a bit paranoid, a bit vindictive and 
hateful, and a bit down on most things related to the USA.

He often mentions the delay in his posts, and that could be caused by a 
number of things.  Normal web propagation and/or listserv software behavior 
is pretty unpredictable, and delays are common in posts to reflector mailing 
lists.  Further, if he is using an email account different from the one he 
originally registered on Radsafe, then the moderator must approve each post 
(this happens to me when I slip up and use the wrong email account from time 
to time).  Finally, Franz may have irritated the list owner / moderator with 
his nasty style, and he may have been placed on moderate status.  Only the 
owner / moderator would know for sure, but who could blame him if he has 
placed Franz (and a few others of us) on moderate status?

Can anyone explain to me,
why Franz is on a radsafe list of "persona non grata" (it has nothing
to do with radiation protection). I think Franz has a lot to
contribute.
