I tried ur plugin, which seems to be a very good development effort.
However I experience problems due to the encoding of the compressed JavaScript files. I am normaly using UTF-8 encoding in Firefox (or IE respectively), which does not seem to be compatible with ur plugin. It works though if I switch to Western (ISO-8859-1).
Are there any ways one could fix this? I tried just saving the file as UTF-8, but it did not do the trick.
I finally found something that I had been looking for... a Spell Checker for Serendipity.
