About a week ago, there was discussion in the CB about how to modify the appearance of all content on PerlMonks authored by a given monk. For example, turning all of bart's posts pink or hiding all anonymonk content (both actual suggestions from that discussion).

While several people pointed out that those could be done with various CSS tricks, it was also noticed that there are at least six different classes in use within the Monastery used to identify an author by their user number (####):

     node-from-####    Newest Nodes
     nnt-auth-####     R.A.T.s
     pmnote-####       Replies
     chatfrom_####     Chatterbox
     auth-####         Best/Worst Nodes
     user-####         Online Users (not strictly "authoring")

It would be nice (IMO) if these could be unified into a single class name, but not being devilish and therefore not having a clue how much effort (or side-effects) that would cause, I'll settle for a quick example. This won't let you flag everything (for instance, results in Super Search are not tagged for per-author styling, nor are the section summary pages like The Monastery Gates), but it covers a large fraction of the content a user can post. Place the following CSS in your Display Settings (scroll down to the textbox labelled "On-Site CSS Markup") to turn all of NodeReaper's content (that you can) bold:

.node-from-52855 {font-weight:bold;}
.nnt-auth-52855 {font-weight:bold;}
.pmnote-52855 {font-weight:bold;}
.chatfrom_52855 {font-weight:bold;}
.auth-52855 {font-weight:bold;}

Update: ambrus notes that this can be contracted still further.

Update: duelafn golfs it down more (but also gets signatures in the process).
