It looks like I've figured out how to encorporate formulas into html: (many thanks to Arthur J. O'Dwyer and Jeff Grafton for their patient explanations).
Now, how do I get rid of that annoying border?
Update: border issue solved (thanks to Jeff & Peter Nelson). I can now blog with the big boys...
Update II: My list of benefactors now includes Adam Schloss -- thanks to everyone for helping me figure out how to do this. The LDP vs COM post has been redone, and is now readable!
