This might be a bug, but will discuss it here first. Clicking on an old "?" or going to a create link but new Markdown content exists, should not go into "create" mode, but should do a regular "edit".
I belive that currently it does a redirect to the new static web page. At least that's the intent of the code. --Joey
Try at your site:
?page=discussion&from=index&do=createIt brings up an empty textarea to start a new webpage -- even though it already exists here. --reed
Ah, right. Notice that the resulting form allows saving the page as discussion, or users/discussion, but not index/discussion, since this page already exists. If all the pages existed, it would do the redirect thing. --Joey
