Guys my apologies,
I just changed the permissions to allow file uploads and for the Wiki to be editable by subscribers to this group. Vic was kind enough to point out the issues, so I've made adjustments.
For the uploading of files, bear in mind our limit is 1GB for the group. If we get close to that limit, I'll change the permissions, do some rearranging to gain space, and introduce links to external storage for older/archived files, then flip permissions back to upload again.
