I have come across a neat little plug-in for MS Internet Explorer 5 and above. It is a spell checker, just like in an email program. After you type your message into a text field on a web page, you will be able to right click on the text and a spell checker will pop up.

Go to this web page, click on download and save the file. Then open the folder where you saved the file and double click on ieSpellSetup251106.exe. It will install the plugin. Then you will be able to spell check anything that you write into forms on websites.
