Torley is the only Linden that I know who publishes her e-mail address in her forum signature, and who actually replies to e-mail. But Torley can't answer all issues, and has no authority on policy changes and the like.
Every other Linden that I have tried to locate contact information for seems to hide their e-mail address like a precious gem, and if they have a forum Private Message mailbox, they often don't read it.
You don't want us bumping ignored posts in Linden Answers. You killed the general forums, where we could raise general questions. You won't allow us to create topics in the Blogs. We need SOME way to escalate issues to the attention of a Linden that can actually affect the issue.
Please provide, somewhere on this website or in a WIKI or a FAQ that is easily accessible from this site, a list of what Lindens do what tasks, and what their current, valid e-mail address is.
I saw a list like that in a WIKI or some such place once, apparently compiled painstakingly by resident efforts. But I have no idea how to get to that page any more, or even if it still exists or is at all current.

Follow-up in response to Torley:
Thank you Torley.
Knowing that I should send e-mail to the Linden's first name "@lindenlab.com", for example "robin@lindenlab.com" for Robin Linden, or "daniel@lindenlab.com" for Daniel Linden, does help somewhat.
I can empathise with the e-mail flood, dear. I have worked in public-facing support roles where my daily e-mail queue was, without exaggeration, as high as 300 to 500 messages PER DAY. And I was expected to at least read all of them, and to act on them as needed. And I did. I highly recommend keeping a "to do list" for unresolved issues, so the flood of new messages does not overwhelm the fires that have already been lit beneath your overworked office chair.

Please do see if someone at Linden Labs could put together a roles and responsibilities list. Even something simple like this would be very helpful :
Torley : Public Liason
Ginsu : LL Lawyer
Cube : Coder, bug squashing
In particular, who sets Linden policy on issues? To be specific, I am still trying to get an reply to my question on why the "2 accounts per payment method / 5 accounts per household limit" is still arbitrarily and only occasionally being inflicted on people, when it no longer exists in the TOS or Registration process, and when it makes no sense in light of unlimited open registration for unverified accounts and the end of stipends for free accounts. Phillip Linden passed it back to you and to Robin. But is Robin the person who can actually make a policy decision on that? If not, who can? Apparently not Phillip...
