A couple of minor things in the commenting department:
– For those of you using the preview comment function, I’ve made it a bit clearer that you’re previewing your comment and that it is not saved.
– I’ve also made it a bit clearer on what HTML you can use, including a handy link to an off-site reference page. If you insert HTML character/symbol codes, WordPress will pass that along as HTML and render the appropriate character/symbol.
