i live in dread of self management on our site since the people who would clamour for it are the tyrants. We have a few problems with terrible unworked plots and tenants hanging on to their plots for years, depsite doing NOTHING, year on year BUT, there are some absolute bullies as well who are adamant that one size fits all - I would be kicked off for not growing just fruit and vegetables. A handful of people managed to get CCTV on the site, despite vigorous opposition from others. mostly though, many of these arrangements end up in the hands of power mad busybodies. On the whole, i prefer chaos and anarchy.
