I am trying to set up a website for our Old Age Pensioners' Action Group using Sitefinity. I have most of it up and running but I cannot get the forum to work properly. Although I can put up threads, other members of the group are barred from doing so. Please, please, what have I done wrong and what can I do to correct it? The site is www.nottinghampensionersactiongroup.org.uk.
Any help or guidance would be most appreciated.
