FYI, LadyCFII, the link in your post above to the article is fine; however, the link on another article on Zendesk linking back to the forum on plant experimentation and another thread is broken. Two relevant forum threads are referenced and having read through most of those guides, I'm fairly sure only one article had two such links to threads by players, so that could narrow it down.
Would like to be more specific, but when I tried to make that comment on Zendesk, I was required to sign in (guess *that's* why no one has indicated they found the information helpful or not, lol), I decided to do so with Twitter. Another pop-up telling me to enter my email; another telling me my email matched another profile on file. I thought the message meant my profile from this forum, so I used the password I use here. INVALID. Well, now I cannot get past that pop-up, so I cannot confirm which article contains the broken link
I look forward to meeting those merchants as I've never had any visitors to town yet. Guess I need to finish up all those partially-finished repair jobs.
