gPress adds new geo-relevant layers to WordPress, allowing you to create your own location-based services or to keep track of your own personal geo-tagged journies. Even in its beta state, you can presently geo-tag posts using native WordPress Mobile Applications, or create new geo-located places using custom post types, featured images and descriptions, add geoRSS functionality and integrated with BuddyPress and Foursquare.

The future of gPress is one where you can develop your own completely customizable, fully-interactive and entirely immersible geo-relevant social-layers using combinations of movements, actions and consequences whilst geo-tagging, trailing and interacting with locations, people and objects. Create new geo-relevant states of social-roleplay by defining language and lingo, customizing context and integrating with other social-networks.
