Postica is an online tool that allows users to better organize their documents, without having to print them off. Postica allows users to create sticky notes, attach files, and share those files with friends. Users first create the sticky note, personalize it by color, and drag it to the corresponding document. Postica remembers the chosen color on any computer, so all people looking at documents view the same colored sticky note. Furthermore, users may upload chosen photos or documents to the sticky notes. Lastly, these sticky notes and documents may be shared to other friends, even if they have not created their own Postica accounts.
