For those of you reading who are actually BSFA members, an important announcement: a chunk of the last mailing (with the Clarke Award issue of Vector) seems to have gone missing. As Peter says:
We therefore urgently need to know which members have received their magazines and which haven’t. If you are not among the 20 or so members who have already let us know, please could you therefore email us, giving your name and (if you have it available) your membership number and whether or not you have received your magazines. If you know any other BSFA members who are unlikely to see this message, please could you also ask them to contact me or one of the other BSFA officers with the same details.
We may also be contacting some members directly over the next few days, particularly ones where the information might give us a clearer view of which members have received their mailings and (in particular) which probably haven’t. We will, however, try to make sure that if you have already been in touch with us about the mailing, we don’t ask you for the information again. But even if we don’t contact you, please do contact us – so we can work out how many members haven’t received the mailing and just who they are.
Note that we want positive and negative datapoints; we need to know the extent of the problem.

Have emailed; Vector still conspicuous by its absence in this neck of the woods.
