Okay, so if you need to read this, you have or will soon have the necessary programs and info, so I won't go into that.
To make a post, go into the HTML document with notepad++.
DIRECTLY UNDER THE PART THAT SAYS
[tt]<div id="stuff">[/tt]
PASTE THIS
[tt]<div id="authorYOURNAMENOTINCAPS">
<h1>TITLE</h1>
<h3> Author: Yourname </h3>
</div>
<hr>
so hey this is an update text lololol
<br /><br />[/tt]
Then overwrite the old html file with your new one via filezilla.
