Hi Eric, Why not stick a post to the top that lists the rules of posting? example: here <https://webapps.stackexchange.com/questions/81119/how-to-pin-a-topic-in-a-google-group>
Also, it seems making "categories" is possible in google groups: example i found on google <https://groups.google.com/forum/#!forum/rg-65-uk/categories> -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
