It’s important to note that there’s a DIFFERENCE between an LFG Listing, that Lists groups looking to be filled, and LFD that searches for a Group, for you and auto-teleports you there.
I created a thread asking for an LFG Listing, and it turns out, it was already a feature in BC. Again, a LISTING NOT an LFD Tool that auto searches, auto fills and auto teleports you:
