Hi Kirill,
First off apologies - I have not programmed for a loooong time, and so this is a first time Github post, questions2answer use, permissions2categories use all in one day. I do apologies if this isn't the best way to ask the question I have - if so please point me in the right direction.

Second off, a huge thanks for taking the effort of making permissions2categories public!

My question is whether what I'm trying to do is actually supported by permissions2categories plugin or not.

Basically I want some categories to only support creation/editing/deleting/recategorizing actions by higher privileged users. Is this possible? Out of the box, permissions2categories just hides entire categories from lower privilege users - whereas I want everyone to be able to read everything. I have played around but couldn't get it to work - perhaps if I rolled my sleeves up and did something inside qa_categorymetas? Thanks in advance for any help.

See this use case :
http://www.question2answer.org/qa/29188/admin-only-categories
When asking a question the category picker should not show up a category if the user has not the permission for that category

is this plugin useful to set privacy to a category of user (a post will be visible to only the user who asked the question and the admins)

For meanwhile I did a core hack to qa-feed.php. I added an if to check for this catgoryid.

//  Build the inner XML structure for each item

If ($question['categoryid'] == 14) {

} else {
$lines[]='';
$lines[]='<title>'.qa_xml($titleprefix.$question['title']).'</title>';
$lines[]=''.$urlxml.'';

    if (isset($htmlcontent))
        $lines[]='<description>'.qa_xml($htmlcontent).'</description>';

    if (isset($Author))
        $lines[]='<author>'.qa_xml($Author).'</author>';

    if (isset($question['categoryname']))
        $lines[]='<category>'.qa_xml($question['categoryname']).'</category>';

    $lines[]='<guid isPermaLink="true">'.$urlxml.'</guid>';

    if (isset($time))
        $lines[]='<pubDate>'.qa_xml(gmdate('r', $time)).'</pubDate>';

    $lines[]='</item>';

}

We are using this plugin to hide post with an "建築家のみ" category (This category is for admin only, I attached screenshot) from other users, but this plugin has not been updated for 2-3 years.

If you will go to this link http://kenchiku4.com/index.php?qa=questions&start=6 you will see that some post is not here but you can select the "2nd" page of the pagination but If you login as an admin you will be able to see that there are post on the 2nd page. The reason is that some post in 2nd page has a category for "admin" only.

We set that there should be 6 posts per page in the pagination.

Has anyone encounter this before and how do you fix it? It would be great if you could help me or suggest something.
