I'm pretty new to this so I'll need a lot of help.

You should go into the directory of the skin you are using and find the _main.php file. Open it up with an editor and find the part that is labeled the Sidebar. It's probably going to begin with a div tag labeled bSideBar. You can safely delete the entire sidebar and keep the main post area. That might be all you need.

Give it a try and if it doesn't work let us know...

if I do that though, then people going to the main blog http://www.creativewebsights.com/b2evolution/blogs/index.php?blog=6 The calendar won't be there.

See I want the sidebar in the blog when you got to the main blog http://www.creativewebsights.com/b2evolution/blogs/index.php?blog=6 but not there when you go to http://www.creativewebsights.com/journal1.htm

This is not too difficult. All you need to do is add a little code to check for a specific parameter (I'll call it 'nosidebar'), and hide the bSideBar div if it finds that parameter. Then, you pass that parameter from the IFRAME in your website.

In your _main.php file, add the following code, just before (above) the </head> tag:

<?php if ($_GET['nosidebar']) { ?>
<style type='text/css'>
.bSideBar { display: none ! important; }
</style>
<?php } >

Then, change your IFRAME tag in your website to look like this:

<IFRAME NAME="cal" SRC="http://www.creativewebsights.com/b2evolution/blogs/index.php?blog=6&nosidebar=true" frameborder=0 height=780 width=100%></IFRAME>

The end result should be that your sidebar is hidden whenever your page is called within the IFRAME of your website, but it shows up normally otherwise.
