I dont know right word for this , can"t we set up a timer for sticky torrent? for example , make this torrent sticky but after 7 days no more sticky

very clear

It can be done via Cronjobs.

Not 100% tested, but should work...

1) Upload RemoveSticky.php into library/cron folder.

2) Goto Admin CP > Dashboard > Cron Entries > Create New Cron Entry

-- Allow cron entry to run automatically when scheduled: YES

-- Cron Title: Remove Sticky

-- Cron File: RemoveSticky.php

-- Cron Function: RemoveSticky

-- Cron Run Period: 0 0 0 0 1 0 (Means 1 hour)

3) Save.

That's it!

but this is for all sticky torrent ? i want to make this only for specified torrents ( tv series etc.)
