I just retagged a very simple question about how to calculate a percentage that was tagged as calculus, logic and "number".
The user only registered today.
Is there a way to add a feature that when a user with low reputation, or new, or first time posting to some tag (or some nice combination of these) that before you can actually post you are presented with the wiki excerpt of the tags you use.
This, combined with maybe having a "weekend of tags" in which the community will uphold a project to write tag wikis - at least for the front page tags, we can help better categorization from the users without high rep/mods running after users and cleaning up the mess.
