I noticed that in 1.8+ texts like titles, activity names etc. do no longer support html tags. I found this quite useful, even that I am aware that it is a kind of a nasty tweak...

For instance, I used to emphasize some specific activities by typing something like "<b>My emphasized activity</b>" or I created some links to specific courses where I typed the name followed by a key image (to indicate that they are not publicly accessible): "My restricted course <img title="restricted access" alt="restricted access" src="<pathtothe>/key.gif" />".
