In the interest of preventing spam, the function that allows users to send e-mail to other users is now disabled for all users. Users who wish to be able to receive e-mail from other forum members can still enable this function by going to profile in the top menu, then settings, select "Hide your e-mail address but allow e-mail via the forum." and update profile to save the setting.
This function is different from private messages, which are not affected by this change and work just like before.
