Categories are two tiered: US State > US City.
When on the listing for a city, you should see (1) the jos_sobi2_categories "image" for that city displayed to "brand" the community page. This image already exists as part of the SOBI2 table. Just need to identify the "current catid" for the listing page, and query/echo the image based upon the catid.
(2) local advertising that can be configured (updated, added, deleted, etc) from the J! admin backend. Counting click-thrus, impressions...etc are not even required for this project. Should have the ability to assign a url (open in new window) to each banner ad located on the city listing pages. The advertising will be unique (not random) for each city category; assigned to the that sobi2 category in the backend. Prefer to have these ads to have the ability to display in the J! modules, but it will be acceptable to display them within the sobi2 template, since that might be easier.
I may also want to have a modification to the sobi2 search. I want to be able to search with a keyword filter, using the existing keyword assignments available to each entry in the SOBI2 component. I want to do a combo-filter on STATE > CITY > KEYWORD (such as : Illinois > Chicago > Bicycles).
