Very helpful article. Thanks for creating.
Is it possible for a Wiki contributor to add his/her name to the tag list? If yes, in which cases?
Love it!
"help" and "troubleshooting", What's the difference?
Yottun, "troubleshooting" is twhere you're learning about how to troubleshoot a specific problem. "Help" is an article about a Help feature or Help content.
Luigi, yes. I would use it when you author the article. Otherwise, it's going to confuse the author if you merely made a small edit on an article. There are times when the author doesn't do most of the work or just starts the stub. In that case, I think it's fair for both names to be on it.
Thanks!
