Firstly, we wish to bring everything under one roof.It has been confusing to new members to have a discussion forum that is hosted on a dis-similar web site, and with it's own separate login procedure. Having the forum built in to our web site removes this problem, and makes life easier for the admins who have to answer all the emails seeking help logging into the system. One log-in, one web site - Simple.
The second reason is to save on costs. The Hover club currently pays $20 per month for the old forum and it's photo gallery. These tools are built-in to our web site, and cost us nothing beyond our normal monthly web site maintenance costs, so it's a $240 per year savings for the club.
