Forum looks great - thanks Steve
FYI, if the Subject is left blank, the user cannot post the message but there's no error message that I could see
I get the error message you see in the attached image. I really wish it has drag-support for dropping in images. And, I am not used to this HTML editor. I will see if I can swap out the editor for the one that is used on the Alpha Forum, which is CKEditor, something I use quite a bit.
(Actually, I do not see where I can attach or upload images. I have to go check!)
EDIT: The Attachment and other options button appears in the Full Editor, not the quick editor. And, it does allow drag and drop file upload.
