If you have paid close attention, you will have noticed that we are now using the new "Download on the AppStore" badges as provided directly from Apple's Developer Resources (requires login).
Currently, none of the Mac OS X applications are signed. To run them on Mac OS X 10.8 (Mountain Lion), you would have to enable the option to "Allow applications downloaded from: Anywhere" in the General pane of the Security & Privacy options within the System Preferences. Or at least, you would have to enable that option temporarily for your first launch of the applications; then you can change it back to its previous setting.
Note, however, that TrashLater Server does not interfere with GateKeeper since it runs as a "launchd" background process. It therefore continues to work just fine even for Mountain Lion.
