Hi all,

I agree that privacy/security shouldn't be limited to the privacy /
security section, but we probably want to have one central location which
contains references to all security/privacy issues mentioned.

On an unrelated note, I had been thinking that given the TAG's recent
finding on unsanctioned tracking, we might want to add a question:

*"Does this standard enhance an attacker's ability to perform unsanctioned
tracking?"*
While it isn't perfect, I feel like it would capture a large set of
behaviors (fingerprinting, supercookies etc) that are used to collect
information. As we've all seen, defining things like what is personal
information can be difficult, so focusing on problematic collection
behaviors is one way to solve that issue.
