There are several ways to contact the InterNutter, depending on your urgency.
If you want to find the InterNutter quickly, you can go to the bulletin board, easily found by clicking the words "Bulletin Board" over on the left. From there, find the latest 'Nutter post and use the nifty little tag at the bottom of said post to send her a PM.
Should the 'Nutter not be browsing her own BBS [a rarity!] then you can try leaving a message on the message board - also hidden in plain sight like the BBS. The 'Nutter will get back to you on the same forum as soon as she notices that the content has changed.
If you have ICQ - or some IM software that can handle ICQ - you can drop the 'Nutter an instant message to the ICQ number 10698750.
And if you *really* want to risk it, you can send an email to cat@internutter.org
You will not be ignored. However, replies might be delayed for a very long time. Despite appearances, the 'Nutter *does* have a real life, y'know...
And if you really, really, really need attention *right* now:
