In the past, many admins/sysops have wanted to be good leaders. And this is the right page for help!
1) Always be kind and helpful.
2) If a wiki user is not kind, stay calm and talk it out.
3) Don't try to block users. If that user is furious, just see his/her behavior and talk.
4) Always give your community freedom and control arguments kindly.
If these tips don't work, maybe it's time to block the user. When making a block summary please use a clear description and don't block the user too long. Just give them a warning.
And here's another thought, what if you are not being kind? Would users like you?
Now, in order to stay being an admin, you must be a kind one. See this for your powers and help, admins. Follow my tips and you should be fine (unless there are certain rules). But, if you are not a good leader, wikia staff or another admin can demote or block you.
