Once a Private Topic thread has been started, the only way for another person to be added is by using a SQL query.

• In order to do this, first take note of the tid (topic id) of the private topic that you want to add someone to, as well as the uid (user id) of the person you want to add.

• Then run the following query:

INSERT INTO fbb_pt_participants
(topic_id,user_id)
VALUES('tid','uid')

(Substitute the topic ID number of the Private Topic for tid in the above query and substitute the user id number for the uid.)

• There is a pt_participants table, which in essence stores the topic ID and user id numbers to dertermine what users can access a particular private topic.

Example Situation

We have a private topic with the id # 225.

If user #2, #16 and #180 can access, there would be 3 entries in the pt_participant table. One for each user number, and all 3 would have the same topic id number of #225.

Adding a user is a simple as adding a row to this table.
