Dears,
As I am reading nearly all articles related to Ravounel, I found it's quite confusing to see how far the information is scattered.
If it was possible, it might be interesting to have at hand at least one of those 2 improvements:1. a usable list of fixed geographical tags (defined by Paizo) like Cheliax, Ravnouel, Taldor, etc
2. subforums under "Lost Omens Campain Setting" subforum by geographical location
The Paizo website is a lovingly hand-crafted pile of code that is more than 10 years old. Technical staff have done some re-writes, but there are many improvements that have been on the to-do list for years.
Tags, I suspect, are a non-starter. Personally, I'd vote for a more powerful search function before I'd want tags.
Sub-forums might be useful, but training the users to only post geographic questions there is probably impossible. Geographic questions tend to pop up from time-to-time in James Jacob's thread in the Off-Topic forum, and those answers aren't going to ever be moved to a different thread/forum.
If you haven't tried the Pathfinder Wiki, you might find that helpful. You can even volunteer to add material and help keep it up-to-date. The wiki only contains information from Paizo publications, so it is by far the most accurate and canonical source.
