This script was originally inspired by SE Editor Toolkit. Unfortunately, the toolkit is packaged as a Safari extension and as such is unusable in Chrome, Firefox, and Opera. I had written a PHP script that converted the Safari extension to a UserScript but it didn't work very well and was completely broken on Firefox.
Hence this script was born. It is an attempt to write, from the ground up, a script that performs automatic correction of common misspellings and removes unnecessary "thank you"s in the post (and title). The script also provides a live diff viewer that allows you to see what changes have been made to the post.
Everything I've described above is currently implemented to a usable degree, but there is still a lot more work to be done - so if you are interested, fork the code and help contribute!
