"Last Seen" Column in the Users List
Records when each user was last active on the site (not just when they last logged in) and shows it in a sortable "Last seen" column on the Users screen.
Snippet Library
Users snippets for WordPress
Snippets for user accounts, roles and profiles: extra profile fields, new columns in the users list, last-login tracking and tighter control of what each role can do. Handy for membership sites, client sites and teams with many authors.
BuddyPress: Hide Administrators' Activity From the Stream
Keeps activity created by administrators (such as testing posts and profile edits) out of the public activity streams.
BuddyPress: Hide Noisy Activity Types From the Stream
Removes routine entries such as "became a registered member", "changed their profile picture" and new friendships from the activity streams.
BuddyPress: Last Active Column on the Users Screen
Adds a "Last active" column to the WordPress Users screen using BuddyPress's activity tracking, so you can see who is actually using the community.
BuddyPress: Limit the Length of Activity Updates
Shortens activity updates and comments longer than a set number of characters, which keeps the stream readable and discourages wall-of-text spam.
BuddyPress: Mark Activity With Blocked Words as Spam
Automatically marks activity updates and comments that contain words from your blocklist as spam, so they never appear in the stream.
BuddyPress: Members-Only Community Pages
Sends logged-out visitors who open BuddyPress pages (members, profiles, activity, groups) to the login screen, so the community is visible to members only.
BuddyPress: Send Members to Their Profile After Login
Sends members to their own BuddyPress profile (or activity stream) after logging in, instead of the WordPress dashboard.
BuddyPress: Strip Links From New Members' Activity Updates
Turns links into plain text in activity updates posted by members who joined recently, which takes the reward out of spam sign-ups.
BuddyPress: Turn Off @Mentions
Switches off @mention links, notifications and the mention autocomplete in BuddyPress for communities that don't want them.
Users Online Count in the Admin Bar
Shows administrators how many logged-in users were active in the last five minutes, with their names in a dropdown.
bbPress: Stop Replies to Old, Inactive Topics
Hides the reply form on topics with no activity for a set number of days and shows a note instead, which prevents necro-posting and old-thread spam.
