I agree that one central source like (RISCOS.com) would be very useful.
Although it may seem great to have a number of choice sites to visit for resources etc., but I have experienced missing out on some useful resources because I was not aware of such sites existed until stumbling upon them! By this I mean not only updates, modules, or enhancements, but useful software I did not know existed!
Maybe the "Bundled" packages (something mentioned not too long ago) in our new era of RISC OS could link to this site for updates, but please.... not the Windows style that tells you every day to update!!!
