hi mbday630,
just click on the lever on the right side of the page.
after that, the website's language will swap to the english version.
we don't have a mailing list, but you will be informed about the demo release when the time has come.
when our demo version is finished, it will be available in german and english.
ps:
our current website nears its end, we're creating a brand new one.
only the newsticker stays up to date for you guys, but the rest does not.
if you want to get informed by the newest updates, take a look at our public board
board.dott2.org until our new website goes online.
hope i could help!
