Provide link to the group in which a forum thread is if you don't have access to forum

[Kristina Hoeppner]

When you send the link to a forum discussion to somebody else and they are not currently a member of the group, they just get a message that they cannot access that URL. However, it would be more useful, especially for open and request membership groups to provide the link or at least the name of the group so that that person could join the group.
