new mod, please help [half way solved]

So I'm probably just stupid and I've never done this before, but I have a few problems.

1. How do I give another user mod permissions for my community? Is this possible yet?

2. How come I'm not able to see my own posts? I want to mess with the mod tools, but none of my own posts are showing unless I log out.

I have tried on web browser on my phone, on a chrome book, and jerboa which has zero mod tools AFAIK

I may be missing something and any help appreciated. Thanks.

Edit: yea I was missing something stupid. I had Show Read Posts unchecked so none of my posts were showing up.

I've still yet to determine how to grant permissions
