What exactly does this part do?
Code:
onsubmit="return vB_Editor['{vb:raw editorid}'].prepare_submit(this.inputname.value, {vb:raw vboptions.postminchars})"
I ask because I want to use my own validation method, and you can't have TWO returns on an onsubmit. If I delete this part, it doesn't seem to have any adverse effects. So what does this do, and why is it needed?
