... official thread.
sigh. Can we tighten up the thinking just a little bit?
official (əˈfɪʃəl)
adj
1. of or relating to an office, its administration, or its duration
2. sanctioned by, recognized by, or derived from authority: an official statement.
3. appointed by authority, esp for some special duty
au·thor·i·ty (ə-thôr′ĭ-tē, ə-thŏr′-, ô-)
n. pl. au·thor·i·ties
1.
a. The power to enforce laws, exact obedience, command, determine, or judge.
The phrase official thread is semantically vacuous, as attested by this very thread and the posts made to it.
