When a document (espcially a large document) is modified in SBS/clearspace, the email sent out contains the complete text of the document. In order to know what actually changed, you have to go into the web interface and check out the rev history.

It would be much better if the email that is sent out contained additions in green and removals in red or something like that. Then you could tell at a glance what was changed and not have to go into the doc.

Note that this only applies to articles, not discussions.
