There are memorials for Matthew Ammon associated with the B5 S4/RS4 forum and the Pacific Northwest Discussion. The placement of these memorials on the
index page has them to the right and underneath respectively. It may be an issue in how you distinguish a discussion from a forum, but I don't think it looks right to have those images in different relative locations. Can you pick either to the right or underneath for these images and make it consistent?
Personally, I prefer to the right as it makes use of the white space. If you intend to have images with each forum, you might want to consider what it will look like if all such images are to the right of the forum/discussion text or under it.
