The underlying domain that has the nameservers is still going to expire (it hasn't been renewed, yet). The only hope of this being resolved seemed to be a random new account that spouted rainbows then didn't seem to deliver anything.
forums.pepipoo.com and pepipoo.com will stop resolving (and become inaccessible unless you add the server IP address to your hosts file) around the 30th of November (30 days after the date of expiry). Obviously Joe Public isn't going to know to add the IP address to the hosts file, so they'll just see a name resolution error on their browser.
When the domain becomes available to purchase (if it isn't renewed), and if I can nab it, I'll redirect the traffic here, perhaps with a little landing page to explain whats happened to Pepipoo. But the site will have been offline for 65 days by that point (I think that's correct, might be slightly more or less than 65 days).
Archive.org does have a copy of the site, but it may not be 100% up to date to the day the domain expires.
