Some minor points.
There is no first/last comic links for the archive.
When you click the top banner, it should bring you back to the home page.
There is no 'latest comic' link on the main page. Also, ideally, this should be linkable with something like "www.erfworld.com/latest" or "www.erfworld.com/comic". That makes it easier to bookmark
Also, the page seems non-optimised for wide-screen monitors. There is lots of blank space on either side of the comic. I dunno if this is just because it is different from giantitp where the top banner covers the entire screen and it is just a matter of getting used to it. (In fact, I looked at a few other web comics and none of them take wide-screen into account ... so guess it is just that it is different from the previous site).
