I have been neck deep in Taxonomy, OG, Rules, Contexts, Relationships and many more all week. It hasn’t been very fun but I know that I need to be able to scale this site properly and so, I need to do the research early on.
I need to be able to sort all site content by geography. Specifically by the state that the member resides in. The member will always have only one state. What I really need it a way to autotag a node (as it is being authored) with the state that the member resides in. Here is a really good wiki from drupal.org with a run down of many of the options available.
For my case, it appears that I will be able to use the Rules module and Roles (a core user function) to acheive this. Here is a link to a post that helped me arrive at this decision.
