Anyone who surfs the web with any regularity has had to fill out forms via a browser. To buy something, to contact someone or a some company, to post comments on a blog, to apply for a job...the list is endless...all via web-based forms. The problem is there is no spell check functionality so I always end up going through the annoying step of cutting and pasting form postings to Microsoft Word in order to spell check them before I submit. That is an issue no longer.
Robin Good points out that there are now some nifty plug-ins for IE and Mozilla that will spell check forms for you.
