Here are a few that I could brief,

A2A - Ask to Answer. Currently “Request Answer”, this is one of the great
feature in Quora where you can ask a question to a  specific  person  who  is
best in answering such questions.  For example, I can ask anything related to
aviation to a pilot/aviation engineer on Quora.

BNBR - Be Nice Be Respectful. Attacking a person or their content. That is to
treat  everyone on the forum with respect.  If you disagree with the content,
be patient and have a healthy discussion/debate about it but never  attack  a
person  intentionally/unintentionally  since  you  may be violating Quora’s
policy.

TW - Top Writers.  A Token of appreciation from Quora  who  contribute  great
answers in the forum, which is selected annually.

TQW - Top Question Writer. Again a token of appreciation from Quora for those
who ask great questions.

KPW - Knowledge Prize Winner.  Suppose if a Quoran wins a cash  award  for  a
sponsored question, this badge will be displayed in their profile.

Published  Writer - This is awarded to Quorans whose answers are published in
Quora’s partner websites  like  Forbes,  Independent,  Inc,  Fatherly,  The
Huffington Post, Time, BBC, Quartz and so on.

Most Viewed Writer - Another badge gifted by Quora for top 10 writers who has
most number of views in a particular topic.  For example, if I  have  100,000
views  on  Aviation  and I’m in top 10, I would be awarded with Most Viewed
Writer badge for Aviation.

Answer Wiki -  Suppose  if  a  question  has  hundreds  of  answers  and  you
couldn’t  follow  them  all, Answer Wiki helps you by displaying summary of
the good answers.  Mostly found in survey-type questions.

Quora Sessions - Sessions are events in which writers answer questions  taken
in advance. Before a Session begins, writers open up to take questions on the
Session page and you can post new questions or follow existing questions. [1]

Go Anonymous  -  Some  people  want  to  express  their  views/incidents  and
doesn’t wish to show their identity in a public forum. This feature will be
helpful in such cases but few don’t use it wisely.

or write a blog.

Knowledge  Prize  -  Sponsors offer financial awards for best answers for the
question which they request on Quora.

Credentials & Highlights - This feature replaced “Bio”  which  helps  the

OP - Original Poster.  Denotes the primary person who asked the question.

Quora Moderation/Mods/Admins - A set of anonymous Quora  staff  who  monitors

Topics - The purpose of topics on questions is to allow people with knowledge

wanted to answer it but you don’t have time to answer it currently, you can
use this feature to save it for answering in future.
