Can I suggest integration of GPS tool with blog component such as easy blog and cjblog. The idea is to let user write a blog and can integrate a track as well. It will help folks to write their trip story with track info.
As of now the only way to integrate a track is by using plugin were one needs to know the track I'd which is not possible for a site used who is not admin. I think it can be done by either providing a button to " write article" on the track page after saving them or edit track page which can do this linkage of tracked with article automatically.
Just integrate with editor by providing a button which should open the selectable pop up list of track submitted by user. This way a user can select any track he submitted in his article.
Let me know if this sounds feasible and benefits GPS tool
