Don't those little carets ( the ">>>" things) on forwarded & replied to e-mails drive you nuts? You can set most e-mail clients NOT to put those in if you like. This way, at least the mail you forward / reply to will be easier to read.
Most e-mail clients let you set this preference through an Options or Preferences area.This is how to adjust this setting with Outlook Express, since that's the e-mail client most people use:
1. Click the Tools menu, Options.
2. Click the Send tab.
3. You'll see an area called "Mail sending format".
Under that category, click the Plain Text Settings or HTML settings and deselect the checkbox that adjusts the indenting of messages / original messages. (note that on newer versions of OE that you only need to adjust the Plain Text settings, and this already may be shut off by default).
