We've changed permissions on the Go Fourms, you no longer need to register to have read access. Posting notes still requires membership.
And we’ve enabled and turned on permissions for uploading images.
Apparently the "Quick Reply" editor doesn't support this; the full editor (using the "Post Reply" button at the bottom right) has a little button (of a tree!?) so you can specify an image to upload to our web site, with an automatically generated name that is referenced from your message.
