I have uses 'view source' to look at HTML that specified 3 or 4 fonts, from unusual to common...that way *if* you have the hoped for font, you get the author's first choice..if not, you get something close.Now, I HAVE read about experiments to create a protocall that would check your system to see if you have the specified font, and if not, go to a big font archive and download it to a 'temp' file and install it for that session only. (This happens with many images when you use a Newsreader...it puts them in a temporary file, and deletes them when you close the application)
If they ever work this out, we will be able to almost any font without having 1000s installed.[there is about a 900 font limit in Windows currently anyway]..(but if they DO, I hope they make it a feature you can turn OFF...*grin*,,,some folks' taste in fonts is debatable)
