We present a location-aware messaging system that lets users read and post notes tied to a particular location. We developed multiple clients (desktop, PDA and cell phone) so that users could choose the most contextually-appropriate device to interact with the system. We allowed remote access and authoring to avoid imposing artificial restrictions on users. We report on our initial evaluation of the system. The goal of the evaluation was to explore novel potential uses of the system and to identify users' preferences regarding the different system features. In our evaluation, we found that users were receptive of this system for leaving and receiving location-targeted reminders. They also overwhelmingly approved of the remote access and authoring capability, and suggested scenarios where these features would be crucial. We discuss our experiences building the system and our findings from the initial evaluation.
