I hope my comment earlier today didn't appear critical! I am passionate about sharing knowledge/information, and it is obvious that everyone here is passionate too.
I note that adding an extra button to link to the Wiki appears to have been ruled out by design restrictions. This leads me to make a couple of suggestions. (Before I retired as a software and systems engineer in the computer business, I hated it when people made suggestions like this, instead of stating their requirements. So I'm about to break my own rule!)
1. When we arrive at the home page, we get an offer to "Join the conversation". Could there be an additional
offer to "View the Wiki"?
2. The "Welcome" page is probably where lots of newcomers start. Could it provide a link to the Wiki near the top?
I note that there is a trickle of changes to the Wiki, so it isn't dormant. But it isn't very active. Is that because not enough people know about it? Perhaps, therefore, there isn't a lot of motivation to add to it? Am I being unfair?
I've created a user page for myself, in case I edit the Wiki:https://www.apoe4.info/wiki/User:Barry_pearson
