Hi WU,

For the first video, the teamblog access was set to 'team members only'. This means that only team members can see the teamblog in the teamblog listing.

If you want to allow other non-members to see the teamblog in the listing so that they can join, just enable their permission to do so at the user groups section(http://take.ms/R76hV).

I think even if I allow to view he menu, but I don't open other permissions, whether I can't see anything, I should have a message that "404"

I think the access in the teamblog access setting should determine who can load the teamblog's page and if they have no access, they should hit the 404 with restricted area message.

In other words, for example if only team blog members have access, then only they can load the teamblog page.

Will log this in our tracker so it can be addressed.
