Matt,
Just trying to keep the forums clean and easy going. It makes everything go smoother that way.
It sounds like you've been having troubles with other extensions before JFBConnect, so I understand your frustration. We'll definitely do what we can to get you going quickly though.
For the instructions, I understand there may be some points that aren't as clear as you like. However, the guide is already 13 pages long, which gets flack from other users for being too verbose. If there's something in particular you need clarity on, please let me know. I don't know where you read "Put url here" to make it more clear here, but if it's for a Like button, you simply want to put the URL of the page you want "Like'd". That can be the current page that is being displayed, your home page, your Facebook Page, or even
www.sourcecoast.com if you want. You can let your user's Like anything.. that URL is what giving them the option to do.
The auto-description length is currently hard-coded to 100, as you've noticed. In JFBConnect 4.2 (due in mid-April), there will be a parameter to set that length. To change it now though, you'll need to edit /plugins/content/jfbccontent/jfbccontent.php. Search for "100". That number will be in there twice. On the line that looks like the one below, simply update the number to 300:
$articleText = substr($articleText, 0, 100);
The title, description and image should automatically be set using the JFBCContent plugin. However, if you manually want to set them for each article, you can add the following tags to the article text:
{JFBCGraph title=Article Title} - This will be set by JFBConnect to the current page title automatically
{JFBCGraph description=Look at my article} - This will be the first 100-300 chars of the article if JFBConnect is set to do this automatically
{JFBCGraph image=http://site.com/link-to-image.jpg} - This will be the first image from the article by default
Once you set Open Graph tags, it can take Facebook a few days to 'see' the changes. It won't be automatic if you simply go and hit the Like button. To test what Facebook sees though, you can put your URL into their Debug Tool below:

Hope that all helps, but let us know what issues you run into,
