Suggestion:
Have Discourse AI suggest other Discourse sites.
Many users are not aware that there are thousands of Discourse sites and you may actually like to join some but are not aware of them.

Hahaa yes 
would be quiet the user-unfriendly designer if I was looking for deliberate obtrusive methods. Thx
