I have looked for an addon, which would mandate that a user must be a member for x-amount of days before they can post in a specific forum and couldn't find one.

Any ideas on this?

You could use the group promotion system for this. Create a new group which is allowed to post in the forum and create a new group promotion rule to move members to this group after being registered for x days.

That's what I was going to do if an add wasn't available.

I will need to create a new group - how do I make this the default?

Open conf_global.php in your community root directory and change the member_group variable to point to the appropriate group ID.

I looked everywhere for that, except that file.

Thanks for taking the time to reply
