There's a downloads section to the homestar site
Cool. Though I usually just download the SWF's and use SWFdec to pull out the sounds in MP3 format. Works well for 95% of the StrongBad emails which are just one long MP3. Doesn't work as well when there are other sounds embedded in the SWF that are repeated.
Sadly it doesn't look like the download site has all the SB emails, just selected quotes. Oh well. If anyone wants the SB emails in MP3 format, I can probably host them somewhere... I already graduated so it's not like I'll mind if my school pulls my web page down.
