I think it's all about choice.

The way UBB.threads currently works, it gives me the following choices (as a forum user):

1. Click on the link and have it automatically open in a new window.
2. Force the link to open in a new tab.

What it doesn't allow me to choose, however, is a third option:

3. Open link in same window, same tab.

What I'm basically requesting here is that forum admins be given a choice of a minimum of two options:

1. Keep the current behaviour.
2. Turn off the current behaviour.

That way everyone should be happy. Admins who want to keep things the way they are can do so. But those (like me) who want to offer their users more choice can turn off the open-in-new window behaviour.
