Many bloggers and newsmakers greatly enjoy writing their news, live, while logged directly into their online publishing system. But the more scrupolous and professional ones among them are often forced to cut and paste their content back out of their browser and into another application for final spell checking, before being pasted back again into their favourite online publishing system.

Some have resorted to offline writing and editing directly into Microsoft Word, but as many others will tell you, it is not a good idea to write your content in Word if it needs to be posted later through a content management system.

So, I was delighted to discover two tools, one for Internet Explorer and one for Mozilla (across all platforms), that can help anyone editing text inside a browser do a full spell check in-place, without needing to use a separate application.

These two plugins integrate directly in your browser of your choice and make your online adrenaline-rich fast posting syndrome into something that looks professional as the pro's.

IESpell
ieSpell is a free Internet Explorer browser extension that spell checks text input boxes on a webpage. It should come in particularly handy for users who do a lot of web-based text entry. It allows to store and use your personal word list across all applications, instead of maintaining separate ones on each one. The program installs as a new button in the IE toolbar (as well as a new menu item under "Tools") - abd after having filled any web-based form, it is accessible by hitting the ieSpell button. IESpell pops up as a dialog box, similar to the MS Word spell check. ieSpell also works (right-click menu only) on other IE based browsers such as SlimBrowser, CrazyBrowser, MSN, MyIE, etc. . ieSpell does not contain spyware or adware. It's free for personal use only. Commercial licenses start from USD $15.

Spellbound
Here is the same thing, even better for Firefox.
SpellBound is a spell checker that enables spell checking in web forms (e.g. html textarea and html input elements). This allows you to spell check forms (e.g. message board post, blog, etc.) before submitting them when using Firefox. There are no special system requirements beyond those to run Firefox 0.9 or above and it has been verified to work with Windows, Linux, and MacOS X. SpellBound is available in 43 languages. Free.
