The forums seem to now be settings LSO cookies. That's not good. Those are a security risk and I always have them deleted upon closing my browser. I wonder if this is why I am suddenly losing login so frequently. Most people are entirely unaware of what an LSO cookie is, let alone the security risk they pose.
Adobe/Jive needs to stop using LSO cookies ASAP. Even if they're not the cause of my problems, they should still not be used.
