1. Implementation
The following tracker definitions contain the minimal fields required for a database of offers, and a database of demands, which can be linked through users. In addition, there will be a group tracker for registered users, collecting some extra information from users (like interests for exchanging things, topics they would like to learn from or teach others about). This group tracker will be shown at registration time.
It would be very nice also the change that the user can click on certain checkboxes at registration time (i.e., fields of the group tracker at registration time) in order to let them monitor from the very beggining some general users forum, or community news blog, community newsletter, calendar, etc. I (Xavi) wonder whether this is (or will soon be) possible through the group watch or a_l_e_r_t features or by other means.
TO use this profile with this set of data to pupulate it properly, you need to create beforehand two users in your tiki site: user1 and user2. This is due to the fact that the profiles system isn't able to create users in tiki (at least, so far by the Feb'09).
