Description of problem: This is obviously by design, but I definitely used to notice when the bug reporter was from Red Hat or a vendor or the great beyond, based on their email address, which is now not immediately visible. It was pointed out on IRC that the names are mailto: links, so I believe that hovering over the name will be a reasonable workaround, but I wouldn't be surprised if this bites someone at some point when they don't realize who they're talking to. Another thing to consider is you could highlight non-RHers in a noticeable color (and for instance I could be blacklisted if you like). I'm definitely glad the CC: list is still email addresses, because you can quickly scan it for alternate domain names.
Well the entire reason for the email address changes was to 1) get more screen real estate and 2) hides email addresses from no logged in users to help repel spam robots looking for addresses. The Cc list needs to be sanitized as well for non logged in users but is not yet complete. I will look into changing the email format for logged in users to be instead: Real Name <email>
Should be addressed now. Closing.
