This does not help.
There are sometimes you like to get in contact with a specific user, but on this board its not easy. You can do as win9x has done, add website/google+ etc. But if the user has not done that you can not get in hold of him. Not sure if ZeroByte like publish his information.
This forum is based on phpBB that do has an internal post system. Why MT has disabled it, us up to them to answer.
Using an internal post system is the best way to communicate with other. You do not need to expose your personal information. If you like to give away you personal email, you can do it in a private message, only for the requester to see.
Edit
I did try to access the post module directly, ans there I see that its disabled.
Also if this is correct (my not show last version if docs folder are not updated)
