Activity log

The activity log is a feed of what people have been doing in your space — problems solved, contests joined and finished, comments posted, achievements earned, members arriving. It's on the dashboard as Recent Activity, and See all opens the full list at /<space>/activity, newest first.

It's a good way to see whether a space is alive: whether anyone attempted the problem you published yesterday, whether people are actually finishing the contest, whether new members are arriving.

What appears

Entry	Recorded when
Problem Solved	A member fully solves a problem.
Contest Joined	A member joins a contest.
Contest Finished	A member completes a contest — with their score and rank, when known.
Comment Posted	A member comments on a post or a problem.
Post Published	A member publishes a post.
Achievement Earned	A member earns an achievement.
Member Joined	Someone joins the space.

Each entry shows who did it, a one-line summary linking to whatever was involved, and when. Filter by type to narrow it to the one thing you're watching.

Per member

The same feed, limited to one person, is the Activity tab on a member's screen. That's the more useful view when you're looking into a particular person — what they've solved, which contests they entered, when they joined.

What it isn't

The activity log is about members, not administration. It doesn't record that you changed a contest's settings, edited a problem or granted someone permission.

For those, look elsewhere:

A problem or contest has its own Activity tab, which shows the background tasks run against it — imports, retests, scoreboard rebuilds.
Automation rule runs are in the automation logs.

Two things worth knowing

Entries are worded using each member's pronoun, so the same kind of entry reads slightly differently from one person to the next, and differently again in another interface language.

If the thing an entry points at has since been deleted — the problem, the post — the entry stays, but it loses its link and falls back to generic wording.
