This semester I've been using Notepad++ a lot. I've really gotten to like the text editor quite a bit. HTMLValidator doesn't do color syntax correct when you use a single quote in php files, so students and myself have used Notepad++ as an editor.
I used to like Lemmy quite a bit, but a vi editor is not the choice for most undergraduates. Now I mostly use Linux on my desk, so Lemmy isn't as necessary.
