Currently the only way to block PM is to have admin create a role with PM=0 and manually move user to that role. Also currently there is no option to block email/friend request from others.

In user control panel, add three check box:

1. Block other users from sending me PM

2. Block other users from sending me Email.

3. Block other users from sending me friend request.

In backend DB, just add one more column in users table called "BlockContact"

It can have values "pm,email,friend" for each user.

If it has all three values, it means users does not want to receive pm, email and friend request.

If it has values "pm, email", it means user does not want to receive pm and email only. He is fine with others sending him friend request.

If it is NULL, then they are no blocks.

All this assumes that pm, email and friend request are enabled in Admin settings.

Possible yes but not in 2.0 (feature freeze). You can log it in the issue tracker on github as enhancement for later versions so it wont be forgotten.

It only allowed me to open it as an issue. It did not have an option to open it as enhancement.
