a demo of it is on
http://www.blacksheepbar.com
hen you post a message you will see a spell check button underneath the message area.
Click that and a window will pop up with your message in in. all miss-spelled words are in a select box in red with other options for the word in blue. You then choose your replacements or leave them as it is and click update . the altered message is then placed back into your message!
its quite a basic spell checker and it doesnt handle grammar or bad capitals etc.
But gimme a break this was all coded with no php knowlege at first

any feed back on ideas and options welcome. I know sometimes it does give the best results , but hey I've just learnt how to do it , I'm working on an improved algorith , sometimes it works great

Once I have tidied up the code , written docs and general improved it to handle stupidity and bad setups I will release it publicly
