I use Windows Notepad when writing my webpages. I tend to not like gui interfaces and prefer to do it myself so that if something goes wrong I know where to look to fix it.
There is an excellent Notepad replacement called Notetab Lite. I have used it and can vouch for it.. its very good.
The ultimate free Notepad replacement and a handy HTML editor. Handle a heap of files with a simple tabbed interface. Search files, strip HTML tags and format text quickly. Build libraries of text macros to speed up your work. Formerly called "Super NoteTab". 100% freeware -- no ads and no nags.
