This forum has one issue and one deficiency that specifically bother me, the SPAM filter and message images.
The issue is the forum has an overly aggressive SPAM filter that is quick to remove a message, especially when the poster edits a message. Many times I will not catch an editing mistake until after a message is posted. Too bad because if I edit the message it will likely end up in the SPAM folder. Then I have to decide if the message is worth the hassle of a private message to a forum administrator requesting they find and recover the message or, post a second message asking, "Where's my post?!" Either way a silly mistake ends up bothering multiple people or cluttering up the forum.
The deficiency is the lack of support for hosting animated gifs or screenshots. A poster can insert a url pointer but the image itself is not saved with the message so if the link breaks, the message is likely useless. As everyone likely knows, sometimes a picture is worth a multitude of words.
It worries me that new CbB users can not join the forum and ask for guidance or assistance or just comment on their likes and dislikes. This forum is a huge component of what makes Cakewalk fun to use! However limiting access to this resource does kind of force Bandlab to actively develop their own CbB support system. So maybe this limitation is a way of "forcing" Bandlab to maintain their focus on continual development of their support system.
