Describe the issue

Issues and Planning

advises

"Please apply one or more applicable labels to your issue so that all community members are able to cluster the issues better."

I have Contributor status and I cannot add a label, so something is wrong.

Suggested change

Either remove the advice to add labels or enable users, who are not Members, to add labels.
