Many new and old boards now redirect to hashtags

I changed the system for the Cooking board significantly (particularly with regard to its sub-boards). Most of the previous boards are now just links to hashtags. The reason for this is so that users don't have to choose between the Cooking board and the various vegetable and herb boards.

I also added sub-boards to many vegetable and herb boards that redirect to hashtags on the same topic, for convenience (and you can still use hashtags for boards where this has not yet been implemented, of course).

The new hashtag system allows cross-posting to be more feasible.

So now, instead of going into Cooking->Bread->Biscuit, you just go into Cooking and add those hashtags to your post (and you might also add #wheat or such).
