Each Idea Page has its own Trash, which is located in the Sidebar. The Trash contains everything that you, or any member of your Project Team has deleted from that Page:

In the example shown above, the Trash for this page includes some documents and a sticky note.

The Trash lets users treat Idea Pages as kind of graphical Wiki: any team member can delete any item from a shared Page, and anyone team member can restore any item from the Trash (i.e. put it back on the Page). And if there's something in the Trash that you no longer need, you can remove it permanently using the Remove button. (Note: since Kerika works on a peer-to-peer mode, removing somthing from the Trash only removes it from your computer – your team mates will still have copies of it in their local Trash.)
