# List a thread's messages

A thread's transcript, OLDEST FIRST — the order it is read in, so no caller has to reverse a page — each message with its author's name, mentions, pinned flag and edited stamp. Deleted posts are left out. `limit` defaults to 100 and is capped at 500.

Access class: `def:read`.
