Project creation "restrict access" feature too ambiguous.

Description of problem:
"Would you like to restrict access to this project to certain User roles?"

"Restrict access" implies that no unauthorised user can access the project, ie. view the project at all.
As the feature only applies to translations, it should indicate this clearly somewhere, ideally in the question itself.

Version-Release number of selected component (if applicable):
3.x

How reproducible:

Steps to Reproduce:
1. Sign in, go to $server/zanata/project/create
2. View the lower options of project creation

http://zanata.org/help/projects/create-project/ indicates what this feature does, but certainly wasn't what was expected.
