Doesnt seem possible yet, but hope it gets added.
Having a handful of specific subreddits pinned at the top with RES is the thing Ive missed the most since moving over.

This is not true. I downloaded a txt file posted after the closi ng of the site with all the magnet links and have used it for several movies after and they all worked fine.

Barrage Rogue on WT4 at around lvl 73.
Feeling the grind now for gold/materials and not enjoying NM dungeons as much as rifts but still playing a bit here and there.

What worked for me was going into to the cave, start the first conversation, then run out and wait a bit and go back in. When I went back the group had moved up to the wall.
