We've recently updated the website software, which includes a change for clubs/organisations.
People not currently members of your club/organisation can now create or reply to topics within your public forums (where you allow it).
This means if you don't want to rely on the application form for people to apply to your gang and wish to have your own topic/application guidelines, you can or if you wish for non-members/probationary members to post media activities before you make them members, they now can. (Basically how the old forum sections worked).
I've been through and updated everyone's public and applications forums within their club/org pages to allow public posting.
On another note, it seems there is an issue with accepting org/club rules before joining, in the meantime, I would recommend club/org owners/leaders disable "joining rules" until a fix has been issued.
