Rated 3 out of 5 stars
Some good, some bad. But thanks for what will be extremely useful, perhaps with some improvements.
For example, I tried it in the "what do you think" text box below. Highlighted two words, selected casey : all caps. It did indeed generate all caps -- but did it to the WHOLE text box. It would be better if you could do it only to the selected text.
Secondly, it works only in "plain" textareas. But many forums add some simple HTML mark-up buttons, often using TinyMCE as at http://tinymce.moxiecode.com/
Used together with TinyMCE, Casey doesn't do anything. Perhaps it's unreasonable to expect it to, I'm just pointing out that people who say it isn't working are probably unware that they are not testing it in a "normal" text area. Though of course, it would be great if Casey could be made to work in TinyMCE textareas too.
