Items that have been idle for a while within the space (and not present on someone's private storage space) can be nominated for recycling/removal.
The procedure for this is to put a 28-days sticker on the item, move it to the purgatory table and send an e-mail to the mailinglist stating that you put said item on the purgatory.
If there is an ownership sticker on the item, stating it's owned by someone specific (and not revspace in general), please contact that specific person first. If you have no contact information, contact one of the board-members.
The 28-days stickers can be found on here:
