as written to the dev list, I had the problem to restrict access to some newsletters but not to all. I found a solution, but I am not sure, if this breaks nothing else. Here is the problem:
I want to set up some newsletters: One with access from anybody (anonymous users can subscribe and view the archive) and some others with access only for special groups of users.
On global permission page I set 'tiki_p_list_newsletters' and 'tiki_p_subscribe_email' for anonymous users (this permissions are not available on the object permission page).
On the object permission page for the single newsletter (accessible through /tiki-admin_newsletters.php and the key icon of every newsletter) I activate 'tiki_p_subscribe_newsletters' and 'tiki_p_view_newsletter' for the group of users with permissions on this newsletter.
With this settings I would expect, that an anonymous user browsing page tiki-newsletters.php would see the list of newsletters, in this case showing only the public newsletter. But in this case there is an error (You are not logged in). As a privileged user (allowed to see all newsletters) the page is accessible but empty, not showing any newsletter.
The problem, not seeing any newsletter on tiki-newsletters.php is solvedby setting 'tiki_p_subscribe_newsletters' on global permissions for anybody. But I get a still the problem to put restrictions on the archives.
I was thinking, that setting "tiki_p_view_newsletter" to get access to the archives is the key. I set this permission on the object permissions only. But this is not working. Accessing 'tiki-newsletter_archives.php" is impossible for anonymous users, regardless of parameter nlId set to
the correct newsletter or not. Access is granted only, if permission 'tiki_p_view_newsletter' is set as global permission. But then there are no restrictions possible.
I found a solution by patching some code. I am not sure, that the solution I found has n side effects on other parts, so I put it here for discussion.

Show.tiki.org is in the progress of creating the new instance. Please continue waiting for a minute or two. If this continues on for more than 10 minutes, please let us know of the problem so that we can do something about it. Thanks.
To help developers solve the bug, we kindly request that you demonstrate your bug on a show2.tikiwiki.org instance. To start, simply select a version and click on "Create show2.tikiwiki.org instance". Once the instance is ready (in a minute or two), as indicated in the status window below, you can then access that instance, login (the initial admin username/password is "admin") and configure the Tiki to demonstrate your bug. Priority will be given to bugs that have been demonstrated on show2.tikiwiki.org.
The URL for the show2.tikiwiki.org instance that demonstrates this bug is at: http://. Note that if you get a popup asking for a username/password, please just enter "show" and "show". This is different from the initial login and password for a new Tiki which is "admin" and "admin".
For the install log, see http:///info.txt
Note that if you see PHP errors or a Tiki claiming to be missing third party software, the instance creation is probably not finished. Please wait a couple minutes and reload.
Snapshots are database dumps of the configuration that developers can download for debugging. Once you have reproduced your bug on the show2.tikiwiki.org instance, create a snapshot that can then be downloaded by developers for further investigation.
Snapshots can be accessed at: http:///snapshots/. Note that if you get a popup asking for a username/password, please just enter "show" and "show".Create new snapshot
