So you want a web site? Jottit is ridiculously
simple. The first page you arrive at seems so bare that you might
even think you've missed something but it really is just a matter
of starting by typing something and away you go.
This could be really useful if all you want to do is put some notes
on-line in a hurry. It is a bit basic, though, and you'll want to
move on to some of the other options later but certainly a good
place to start for beginners.
example (using Camtasia, incidentally) is featured on the site
so you can see how it works.
