Using UNIX Solaris 5.7, Linux 5.x, 6.0 (no Windows)
I am new to mule; 

[1] Is there a user group for mule in english?

[2] If I were creating documents which contained a mixture
    of English, Chinese, Greek and Hebrew, would mule be the
    **best** editor for me? 
  
[3] I read of KLyx, a KDE editor which claims to be able to
    handle international languages.  Is this easier or more
    powerful than mule?  

[4] if i save my files in mule, and then want to send them
    to a publisher (who is probably running Mac [cool] or Windoze),
    is there a way to maintain the different language encoding in the
    files and be able to translate the documents to other file formats?

[5] Finally, Is there a standard file format in the publishing world?
