LoJ Watchlist a.k.a. "Buddylist" a.k.a. "Stalker Central":
You can now choose custom members to follow on LoJ and view their most recent ascents, either by date climbed or date logged.

When you are logged in, under "What's New - Recent Content," you'll see a new selection "Your Custom Watchlist."
From there, you will be prompted to add members, using a text search. You can unfollow members by clicking the "remove" link next to members you've added.
Let me know if you have questions or run into issues.
Once no further modifications are requested for a while, I'll add a mobile version.
Happy Stalking!
