Technical Issues with THT website - Can I subscribe to a specific User/Screen Name?

I'm curious if there is a way to subscribe to a particular user. In the same way that I get email notifications when someone posts to a subscribed thread, is there a way to get notifications when a specific user posts anywhere on THT?

For example, my brother is a member on here. He and I like to keep track of whatever discussions we are having with other people about other topics. Can I be notified any time he posts somewhere?

Did this ever get an answer?

Pretty sure it is not posible with this version of software.

I actually want to unsubscribe to threads so that only new posts to a thread or that only a new thread appears.

How do I do this?
