[Alug] Kmail, line endings and char sets

Hi all Still battling with the basics. Do my posts appear with =20 line ends (can't remember if these represent CR or LF)? Apparently they do for some list readers. I am using Kmail 1.2 (KDE 2.1.1, mandrake 8.0). A general question: what is the recommended char set to use? And a KDE question - char sets seem to be set both under Settings>Configuration>Composer>Default Charset (main window) and under Options>Set Encoding in the composer window. How do these settings inter-relate? Finally, I have just noticed that word-wrap was set to 78. I have reset this to 68 and would appreciate any comments about whether this has improved things in any way. cheers Syd
