COMMON is a very large user group for IBM i users.
It holds conferences twice a year. The larger of the two conferences, which is held in the spring time, is also the groups annual meeting.
One of the things COMMON does is collect requirements from attendees. Requirements is IBM-speak for 'new software feature requests'. In May 2015, COMMON launched a new web site intended to make it easier for the Midrange community to submit requirements. One does not need to be a COMMON member to use the web site. http://requirements.common.org Your name, email, company name and telephone number are publicly visible.
