Dumb Questions From A Noob

First of all, I don't even know if this is the place to ask, but I couldn't find anywhere else that made sense...

Second, Kbin looks amazing, definitely the best out of the fediverse, however there are still things I cannot for the life of me find in the UI.

1. Where can I see a list of the magazines I'm subscribed to? A list, not posts from.
2. Why do the thumbnails for posts appear distorted? The have incorrect aspect ratio. Is there a way to fix this?
3. Where can I see a list of local communities?
4. How is microblogging handled differently from other types of posts? Do they all show up on the home page?

EDIT: #5 I don't seem to get any notifications of any sort, visual or otherwise, that I have received responses to a post or comment. Is this the way it's supposed to be?

I have many more, but any help with those for now would be amazing.
