I am trying to create a discussion system on my Drupal website, (yet to be published).
The feature of that discussion system are:
I have node type debate, where a topic is enlisted and the other members will post "replies" hence discussion.
However I am trying to find a module or set of modules which can do these:
1) Set a timer on the node, ie, expires a node after a set time say after a week (I tried module node_expire)
2) After node expiry "replies" are disabled
3) Revoke the node author's permission to edit that node.
4) A user should be able to only "reply" once to the debate.
So basically when that node expires no activity should be possible besides viewing the node.
I tried ACL, Node Access + Rules but they don't seem to revoke the node author's permission.
Thanks :-)
