Why can't I create a superuser login? Why do I have to use a third party?
You can create a Super User login. What you'll get is an OpenID created by Stack Exchange, the owners of Super User. So this isn't really a third party option.
You can also choose third party OpenID providers such as Google, Facebook or Yahoo!
What are your quality standards?
Explaining everything that applies here would take a while, but to summarize in a few bullet points:
- Be clear. If you're asking a question, imagine that not everyone sits in front of your computer to solve the problem for you. See How to Ask.
- Make it relevant. Answer a question only if you can solve the problem. See How to Answer.
- Use proper formatting and capitalization. Use a spell checker.
- Always cite your sources, and quote passages you didn't write yourself.
