This is something that has always bothered me a bit on these forums. If it's feasible, I think it would be preferable to have links posted on the forum automatically open to a new tab instead of navigating the user away from the forum. I can see this being much more convenient because more often than not, a link accompanies or supplements what someone is saying, and I don't want to have to right click and say "open in new tab" in order to stay on the forum page and not lose my place.
The argument against this would be that you can always choose to right click and select "open in new tab" if you really want to, but I honestly can't think of a situation in which navigating away from the forum would be preferable. I'm on another v-bulletin forum that does it this way, so sometimes I'll forget that it doesn't open in a new tab and click on it anyway, then I'll have to go back, right click, select "open in new tab," and it adds like 4 button clicks to something that should have taken one.
I know it's possible because I'm on another v-bulletin forum that does it, but I'm not sure how difficult it is to implement. If it's not too difficult, I think it would improve the user friendliness of the forums.
