To answer your first question, go to the post, that you would like to give Karma to, then look at their Karma, and you will see [applaud] or [smite] to give a plus, click [applaud] to take away click [smite] at times it takes a moment for it to react. If you still have problem, let me know, by PM, and I can add for you.
Answer to second question, only Admin are allowed to enter the back end of the forum. We as Admin can see all. The names and emails are protected for pivacy reasons. Moderators and Global Moderators have no access to them, again only Admin have this access. Only Admin can delete posts, accounts, or ban members.
So, if you need something and if I see that I have that permission to give you that info, PM me, and I will try to help. In you see a post that should not be, let me know or another Admin, and we will get to it, ASAP.
There are many reasons why only Admins see the emails, but I will not totally get into this issue, other than it is mostly privacy.
