How does this site (experts exchange) handle the text area I'm currently writing in, specifically with urls? I'd like to do something similar, I guess after the user submits a question they parse the text for URL's and if one exists replace it with an href etc? Then when we view the question again, only straight html is being rendered? (ie- there is no more text area there right?).
Also, if this box is just a text area, how did they get this light blue font,font size, font type in it?
Any working examples of this would be great,
