A SpudFiles book of records is a good idea, however it's more fitted to go into the <a href="
http://www.spudfiles.com/spud_wiki/">Wiki</a>.
Issue is, most people can not prove various aspects of their cannon such as FPS, so you wouldn't really know who's is highest. At least in the Wiki people could update it as new proof is found for various cannons for various records.
About the Hall of Fame thing, I like the idea but it seems that we already have a ton of sections (forum sections). Too many forum sections makes things confusing, hell they are already confusing to someone that isn't very familiar with this website. Suggestions for this? Maybe the Hall of Fame should be a Wiki page as well, with a sort description and image that links to the full thread here on the forums. This way things could be much more organized into sections, and Moderators wouldn't have to put things into the Hall of Fame, people could just add which ones they think, and if it isn't worth others would remove it.
Yes, I am the guy that owns & operates SpudFiles (along with our extremely helpful moderators).
