And just as quickly, the blinds are drawn again given that there is now an official list. I'll leave the unofficial list open, but I suspect that the few posts we've seen will pretty much be 'it'.
I'm pleased to see (ref JohnR's comment) that the official list is hosted in-house; the reliance on free list providers is a current pet hate of mine, and part of why I set up the riscository.com domain. The (spur of the moment) intention being to offer a free mailing list facility specifically to RISC OS users/organisations/companies, but in this case provided by someone 'RISC OS friendly' (ie me). The cost of the domain and hosting is, essentially, funded by advertising - in that I've taken it out of my advertising budget.
I'll formally launch the domain and offer free list facilities in due course, mainly, once I've done a basic website and decided how to allow people to set up lists. The latter will probably be manual on my part, because I'll want to 'approve' any lists as the idea is for them to be RISC OS related - automating it will enable any Fred, Jim or Shiela to set up a mailing list for any old purpose.
I have done a logo, though, so that's good. ([link])
