An activity wave is a set period, like a week or a month, that has its own hour quota. Only one wave runs at a time. When it ends, its results are saved and the next one starts straight away. Click **Save** after changing anything on this page. The Activity Waves page with Wave Duration, Hour Requirements, Inactivity Settings and the waves table *** ## Wave Duration Pick a Duration Type to decide when waves end. Clear it to stop waves ending on their own. | Duration Type | When the wave ends | | - | - | | Duration in days | After a set number of days (up to 60) | | End of month | At the end of each month (UTC) | | End of week | Every Saturday at midnight (UTC) | | End of every other week | Every other Saturday at midnight (UTC) | | Every X day at Y time | On the day of the week and time you choose | | Every other X day at Y time | Every other week, on the day and time you choose | If the current wave has already passed the new duration, saving ends it straight away. *** ## Hour Requirements and Inactivity | Setting | Description | | - | - | | Required Hours | Hours each member must reach per wave. Leave empty for no quota. | | Custom activity requirements | A different hour requirement per rank. Overrides Required Hours for that rank. | | Inactivity Flag Period | Days without a shift before a member is flagged inactive. Leave empty to turn off. | | Excluded Roles | Ranks that are never flagged inactive | | Inactivity Channel | Discord channel for inactivity notices. Needs a linked Discord server. | | Variable | Description | | - | - | | `{user}` | The inactive member | | `{mentionuser}` | Mentions the inactive member | | `{period}` | The inactivity period in days | | `{lastShift}` | When their last shift was, or "never" | | `{wave}` | The current wave number | *** ## Managing Waves The waves table lists every wave with its shifts and online time. From the current wave you can: * **End wave** early. * **Set End Date** to pick an exact end for this wave only. * **Delete activity wave** to remove a wave and all its shifts. Deleting the current wave restarts it from zero. When you end a wave and automatic [quota infractions](/Department/infraction/settings#quota-settings) are on, Melonly asks whether to exclude members on LOA and members who joined mid-wave, then shows who will get an infraction before you confirm. Waves that end on their own use the Scheduled Wave Ends defaults from the same settings. *** ## Related * [Shifts](/Department/activity/shifts) for how time is logged during a wave. * [Member Activity & Leaderboard](/Department/activity/members) to see who met the quota. *** Still have questions?
