Thank you. Three years later, and this is still current, and an excellent introduction to the various User Support resources. You give it as places to give help,but it also works as places to get help.
I don’t know what you’re asking, are you asking how you can support other users?
If you want to support other users, go to one of those sites, create an account & watch awhile. Learn how the site operates, and when you feel ready to try, step in & assist others.
If you want to get support for yourself, the process is the same in that you go to one of the support sites, create an account & ask a question & seek support. This isn’t a support site as it tells you when you first login
