im not sure what these member titles are and how you obtain them. i'd really like to know if someone else knows, and could explain. thanks.

Read the rules, they are in a pinned thread in each subforum. It's all explained there.

tl;dr version: It's the Temple ranks from Morrowind, you gain them as your post count increases.

Oh every so often you have to fight a moderator to the death to obtain a new title.

or just post a bunch of times. Same with stars.
