Add some logical conditionals to Add New Group and Update Privacy form

[Dadparvar]

Hi,

When we want to create a group, or we want to update privacy of a group, we see this form:


Some logical conditionals is needed IMHO:

• "Allow member posting" and "Allow guest posting" options should be Radio Buttons. How it is possible to set "Just members can post" and also set "Also guests can post"? (As you wrote for "Allow member posting", "If enabled, only members can post content". So guests can't post in this way. But we also can choose "Allow guest posting". So we should be able to choose just one of them)
• when we choose "Secret" in "Privacy", then "Allow guest posting" and "Ask to join with a brief message" and both options of "Membership Approval" should be disabled in form. (Until creator change the privacy to open or closed again)

Without these conditionals, privacy form is a little confusing for users (For webmasters is clear. Because they live with codes and sites, but how about lawyers? those who spend less time for net and so. The get confused sometimes. Even they can't find buttons in pages when we change it place. Of course its normal)
Also something more would be awesome: when a creator choose "Ask to join with a brief message", then a field be appeared below it and creator be able to write a sentence in it. Then if a user wants to join his group, he sees that sentence on the form for brief (Why is needed? because sometimes group admins needs some special info to accept request to join. For example some firms just accept their customers requests to join the group. So they can ask in brief to "Enter your customer ID below and submit your joining request". Now the text is hard coded and in different situations isn't really clear what info should be written in order for joining request to be accepted)
