I've already written some rant about that
here, and I think that Coyo's use of the font tags is acceptable,
but maybe it would be even better if there were two more special tags like
<CODE>, for example
<EXAMPLE_RIGHT> and
<EXAMPLE_WRONG>, and let either
vroom or the user adjust how that stuff is displayed in the preferences (while I must say, using green/red on white isn't a bad idea). But as the Everything engine already allows different themes to be used for each user, it's a really bad idea (IMO) to allow absolute settings for font colors etc..
