Is this a persistent login?

Lo these many, many ages, we’ve been asking why Linden Research, Inc., can’t manage to have a single persistent login across the assorted websites its customers might want to access (secondlife.com, xstreetsl.com, marketplace.secondlife.com, jira.secondlife.com, blogs.secondlife.com, wiki.secondlife.com). Well, they seem to have managed it for SL, xstreet, marketplace, and the blogs, but not the jira or wiki.

On the other hand, I now have to log in *every* *single* *time*.
