Since it seems unlikely Adam is going to respond to any contact, and thus we probably won't get the www.lemmingsforums.com domain, I've gone ahead and registered a new one for this site.
The address is www.lemmingsforums.net
Due to how domain registration works it may take up to 24 hours for this to become fully functional, so in the meantime, this URL just redirects to the current link (lemforums.neolemmix.com); once it's up and working fully, I'll make that the main URL. Don't worry, this won't break any links; they'll redirect properly (eg: if you were to go to http://lemforums.neolemmix.com/old/index.php?whatever=123, it would redirect you to http://www.lemmingsforums.net/index.php?whatever=123).
From what I can tell, it's fine now. Please use www.lemmingsforums.net from now on. :)
