I have just released a toolbar for formatting text with BBcode, HTML, and Wiki code like used on Wikipedia.
It supports a huge amount of features, such as a color picker, 19 different buttons, and a options window to charges how some of the buttons function. And all for just 51.7KB.
So why not get the Text Formatting Toolbar. If you post on any forums, blogs, or help out on any Wikis it could be a huge time saver. And yes I used it for this post.
