It's a cookie 'issue'. I put issue in quotes, because it is the expected behaviour of cookies. It is because when you login to perlmonks, the cookie will only be set (and _can_ only be set) to the domain that you were visting when you logged in. So, the cookie will only be set for one of the following domains (I think I nailed the complete list of possibilities):

perlmonks.org, www.perlmonks.org, perlmonks.net, www.perlmonks.net, perlmonks.com, www.perlmonks.com, ads.perlmonks.org, ads.perlmonks.net, ads.perlmonks.com, 66.39.54.27, 209.197.123.153, perlmonks.pair.com

Basically, I'm guessing that you most likely logged into www.perlmonks.(org|net|com) and the links on your Newest Nodes page point to perlmonks.(org|net|com), which browsers will see as a different domain, so it will not send your login cookie. Two ways to fix it: One, use the same domain name for logging in and pointing URIs to, or if this page will be a private one (where only you have access), you can pass "&op=login&user=Jaap&passwd=xxxxx" in the query string as well. The latter will log you in to any (perlmonks) domain that the URI points to.
