Broadcom's chosen platform for its community site is Higher Logic. Currently, when one replies to a thread, an entire copy of the message to which one is replying is appended automatically to the reply. There is no way for the user to disable this. When a thread gets several levels deep, the quoted messages get longer and longer. This needlessly increases storage requirements for the community site.
It would be preferable if this feature were made optional or completely disabled. If someone wants to quote all or part of a prior message, he can do this using an ordinary blockquote element.
