This issue irritates me much. Somehow after installing wysiwig editor my comment body form turned into rich.. bla bla area. I do not want this but I can not find the place where to turn back comment input format to the plain text (or filtered format). I know how to change filter options for different content types but turning back comments to the simple format simply drives me crazy! Please help - where is this configuration place for comments?
Better Formats will do the trick. Some more details about this module (from its project page):
Better formats is a module to add more flexibility to Drupal's core input format system.
Features
- Set allowed text formats per field.
- Set default order of text formats per field.
- Hide format tips per role.
- Hide more format tips link per role.
- Hide format selection per role per entity.
- Currently only works on Field API fields on fieldable entities implementing core style text processing. The good thing is that is most things in core and contrib.
