Scratch all that!

It is quicker and easier for all involved if users must perform a one-time
registration post (in which their e-mail address, posting handle, and NSP
are recorded, though if a posting handle is used the e-mail address is not
published.) The registration is manually validated by a moderator who
approves all registrations. After registration approval, when the user
posts, the NSP and posting handle are automatically checked against the
record list and the post is approved if a record is found.

Pros:
No delay in postings.
No extra work for moderators.
No easy nym-shifting by malevolent posters.

Cons:
De-registration for abuse can only occur after-the-fact.
