This is one of those situations where I wish you were local so I could give you produce and pickles & jams in exchange to pick your brain on this :)
On first glance: So I could hypothetically make a community here, eg. 'the community herb plot,' and direct people to posts on French Tarragon et. al. via links/QR codes in that community (instance? Is that the right term?)...? If people wanted to post a question they'd have to sign up, though, I imagine...?
I don't think I need to have a long form blog on this; there's probably 74 different herb societies that would have a page for French Tarragon that I could possibly link to, but it'd be nice for folks to be able to ask questions, share additional information, etc in the post containing that link.
Feel free to poke holes in this...or tell me to bugger off...or say "yes, but..." or whatever 🙂
