Obviously the key to timely information exchange is called
communication. Nowdays, anything less than an interactive website is prehistoric.
But any successful message board or forum as such should offer 100% participant anonymity, otherwise nobody will freely speak their mind.
Always the obstacle to such "dedicated" forums is the registration process; it's where the administrator, the webmaster, or somebody connected with the company will learn the participants' identity.
Because the forum administrator(s) could conceivably be or become stooges for management, no participant will be inclined to speak his/her mind fully, or seriously criticize management.
