I just added my .ee account to the mods of !pokemon@lemm.ee from my Sopuli account.

!bloomcounty@lemm.ee I appointed my .ee account after hearing that remote moderation did not work.

I have pinned and unpinned a post in !womenshockey@reddthat.com

I have added a community avatar to !womenshockey@reddthat.com and changed it within a week.

I have been able to do all of those things with remote accounts.

You can mod a community on an instance other than your home, but you have to be appointed. You can only create a community on your home instance.
