Hi Aaron,

I am really sorry for the delay of this reply. Please find my answers from your inquiries below.

When I add an image to a post, I see there is a selection for image source and image size. What are the differences between these two options?

Image source is used to determined the type of image to be used (orignal ~ thumbnail) on the blog post. Image size are used to determined the resizing of the image based on the image source used. The higher the image source and image size used, the better the overall image quality for the blog post.

I have a menu item for showing a Post Frontpage. I noticed that the posts are removing the formating. I have the truncation turned on, but some of the words do not have spaces because in the original post there is a return after the word.

This is actually a correct behavior when you have enabled automatic truncation for your frontpage listing. This is necessary in order to avoid any unclosed html tag that can cause the blog layout to mess up. If you do not want to keep the html formatting of the blog post, you need to use readmore break inside the blog post as a truncation method and turn off automatic truncation for your frontpage listing.

Hope these help.
