I find that the help guides are only good for the very beginning of the setting up. After that, it is a lot of tweaking and I have never found anything helpful there. That is why I post here. I search in the guides first, but 9 times out of 10, what I need is not there.
I was lucky to have already set up my Gallery in September, so a part of the configuration was already done.
It is also a change for my members, but so far, the response is positive as we now have some functionalities they were asking for in bbpress (like the reactions), so they are happy so far. Some of the tweaks are due to the fact that I see the forum as an admin, and they don't so sometimes, they don't see the same thing I see, and I don't know!
