ps...
I've just done a quick test as follows:
Viewed a thread in IE;
Right clicked, 'View source', saved as 'test.html' somewhere;
Opened 'test.html' in Netscape - familiar 'wide screen' problem appears as expected

;
Opened 'test.html' in WordPad, removed all occurrences of 'nowrap', saved back to disk;
Reopened in Netscape - thread appears with text wrapped correctly

;
Reopened in IE, thread also appears correctly (ie no change).
So, if we can just ask Captain PPRuNe to fiddle with the BBS software and remove the 'nowrap' attributes, Netscape users will once again be able to view PPRuNe! Hurrah!
Pretty please?
