details in behavior, a little perspective from the UX [Site behavior][Site Layout]

Hi, it's weird for me to do this as a first post, but I like the idea of giving constructive criticism. I really like the site and I believe there is a lot of potential!.

Yet, there are some issues. For example, I just spent 30 minutes looking for the link to this page or if something similar existed. I was looking for it on the tribe index, why Lounge, asknapzu, etc don't appear on the index of tribes? Shouldn't they have a special category? (Something like "community and interaction") On the same topic of the tribes, It's annoying that the only option to unsubscribe from a tribe, I should click my profile, then to tribe memberships, and then manually search the tribe. Can a unsubscribe button exist on the tribe page? So if I see it on my frontpage, it's just clicking on the tribe and then click on the button. Maybe it's something concerning the philosophy of this place that I don't know, If that the case then I'm sorry, but I don't think that it's a good idea to punish the user for exploring different tribes.

And maybe this is nitpicking, but it's the third time that I click on the notifications icon thinking that it's something to see the list of my tribes or something alike.
