User blog comment:RansomTime/Assistance Assistance - best practices for helping out on Community Central/@comment-1038387-20160714130116

I think you can help out even if you don't know some things, you can ask questions for clarifications. Just so that, by the time other people come to solve the issue, they have more info to go on and don't need to ask as many followup questions.

Also, when you tell people to use Special:Contact, include useful notes they've got to add. They can't access things? Tell them to include links, browser info, whether they've got custom css. That will help.
