Follow sharkbait's idea, and remember to change the selection scale and scaling size of the unit, so it blocks the path that you want, because the model might be big, but the collision size might not be there, and the gate/farm might not be big enough to fit the gap.

I'd say give up on the idea and be happy without health being displayed.
If you insist, however, then create another unit with no pathing (use the pathing map for a shrub or something else walkable) and the model of an opened gate. When the unit with the key approaches, remove the gate and replace it with the opened one.
I am working on getting access to the old news portal under a different URL for those that would rather use that for news before we get a different news view.
It is OK though for the main page to open up on the forum in the view it was before. As long as the portal has its own URL so it can be viewed that way I do want to try it as a regular forum view for a while
I switched it to a "Standard" article forum. This will show the thread list like normal, but the threads themselves will have the first post set up above the rest of the "comments"
