There are four ways to take something away from a member, and they're not interchangeable. Disabling stops them signing in and is reversible. Marking them unofficial keeps them in the space but out of the rankings. A penalty withdraws named abilities until a date. Deleting erases them, permanently.
All four need permission to change members, and all four are reached either from the row menu in the members list or from the Controls card on the member's screen.
A disabled member can no longer sign in or reach the space. Their record, results and history stay exactly as they are.
Open Members and find the person.
From the row menu, or from Controls → Status on their screen, choose Disable.
Confirm.
Their status badge turns red, their screen carries a red banner with an Enable button, and the link to their public profile stops working.
The same dialog has a Set active period tick box. With it ticked, you set Active from and Active until dates instead of disabling the member now, and they're treated as inactive outside that window — useful for accounts that should only work for the week of an event, or that shouldn't work until term starts.
A scheduled period never raises the inactive flag itself, so a member outside their window still reads as Active in the record. They are nevertheless reported as inactive, and refused, whenever they're actually looked up. If you need someone stopped right now, disable them outright rather than backdating the window.
Enable, from the same menu or the red banner on their screen, clears the flag after one confirmation.
An unofficial member is excluded from official rankings by default. They still take part, still submit, and still see their own results.
Open the member.
On the Controls card, use the Unofficial row — Mark as unofficial, or Mark as official to reverse it.
Confirm.
The change doesn't touch results in contests the member has already taken part in. The flag is applied when a participant record is created, so it takes effect from the next contest they join. A member also counts as unofficial in a contest while a penalty carrying the disqualified restriction is in force.
Disabling is all-or-nothing. To stop someone commenting, voting, asking questions or submitting while leaving the rest of the space open to them, add a penalty instead: it lists the abilities to withdraw and the date the restriction lapses. See Penalties.
A login link signs a member in without a password. It's for the person who can't get in the usual way — a forgotten password on the morning of a contest, an address they can't receive mail at.
Availability: only in spaces that keep their own user database, and only for an active member owned by that database. See Identity providers.
Open Members and find the person.
Choose Create login link from the row menu or the header menu on their screen.
Copy the link from the dialog, which also states when it expires, and hand it over.
The link is valid for fifteen minutes and may be used once. Issuing a new one invalidates the member's previous link, so generating a spare "just in case" breaks the one you already gave out. It's refused for a member whose identity belongs to an external provider, and for a member carrying a penalty that restricts signing in.
There is no impersonation feature. A login link signs you in as that member, so use it by handing it over rather than opening it yourself.
Deleting ends the membership and erases the member's data in this space. It cannot be undone — take anything you still need out first.
Open the member.
On the Controls card, use Delete member — "Erase the account and all data". It's also in the row menu and the header menu.
Confirm.
Nothing happens to the person's Eolymp account or to their membership of other spaces. Where identity comes from an external provider, only the membership here ends.
If your reason for deleting is a seat you want back, disabling is usually the better move and keeps the person's history. A member occupies a seat by signing in during the billing period, and a disabled member cannot sign in. See Quotas and limits.
