Question: Archive and Rating
As already said, Flatboard stores the data in files, not in a database.
Both have their advantages and disadvantages.
If one displays all the subjects in a single page, this will solicit a rise of server load with all the disadvantages that go with (slowness of loading, quota depletion ...).
You can edit the plugin at your convenience, but I can not be held responsible for providing the changes to do this.
The Rate plugin is not optimized for this case precisely.
