OK, figured that out.
Actually would like to remove the Top Menu with "Photos" "Manuals" etc completely.
Any hints?

Hi @dashs,

Just uncheck the "Include in public blog list" parameter for each collection that you want to hide from that list (http://b2evolution.net/man/features-others)

Sorry, I can't see anything that says "collections".

After clicking on every option:
Structure->Blog-name->Features->Other would be a better path.

At the end of the page I liniked above is a note with the path that you need to follow.

Note: this view could be found at b2evo > Structure > [Collection] > Settings > Features > Other

Thanks Manuel, I went there but did not check the entire page -- oops. Not too perspicacious.
Now the top_menu has two instances of my blog (Nutjob) in it, one for the naked URL and one for the URL with blog1.php.
Is there a way to remove the second one?

You can change the "Blog for info pages" to "No blog" in the "Site Settings" view ( http://b2evolution.net/man/site-settings ). The visibility of the whole common header and footer can also be controlled in that settings form.

Hmmm -- Top line still has two instances of "Nutjob". Is that in some unordered list where only one of those entries can be
inserted?
OK -- setting site_skins_enabled off will remove the menu completely. Missed that at first.
Thanks for your help.

I'm having a basic difficulty understanding how a normal (or trusted) user issues posts.
When I log in as such I see no way to compose a new post from the Home screen. How should that be done?

There are many factors that determine who can post in a particular blog. This page would be a good starting point: http://b2evolution.net/man/user-permissions.

You created a new post ( http://forums.b2evolution.net/unable-to-authorize-a-user-to-post-to ), so please let's keep talking about the permissions there in order to close this one due to your original question has been answered.

Thanks.
