The sticky thread you mentioned,
https://www.backyardchickens.com/t/16110/required-suggested-reading-for-the-byc-forum has the list of tutorials in it, in the document labeled FAQ, item #2. It's been updated to include information about the new platform. I just went through that post and did not find any broken links. However -- we are finding broken links scattered around the site, and fixing them as we find them, or as they are reported. Evidently this happened during the conversion. If you still find broken links, please point them out.
On lists, if you are trying to make a personal list of your items, like a grocery list, you're right, I think. I don't see a way to use it except to make a list of things here. Of course that database will grow as people add more and more to it. .
And yes, breeds moves you over to reviews, which includes breeds and products like incubators, for right now, anyway. I know Rob has plans for that area.
Is there something in particular that you want in your sig line?
I know people are having some trouble with the new search. I also know that powerful search engines have a learning curve -- and I'm not very far up that curve yet, either. But it's one of the things members asked for, over and over, on the old site. I guess now that we have it, we need to learn more about how to use it.
Don't give up, just take it at your own speed. Or at least that's what I have to do! It doesn't take being a Rhodes scholar, or we'd all be in trouble. I still find something new most every day.
