With regard to starting a thread on "Men's Shed" - been there-done that. The result was a whole lot of replies which could be summed up as "There used to be a lot of men on here, not sure what happened to them".
I guess what I am advocating, perhaps clumsily, is that it would be nice if posters paused for an instant before pressing the SEND, and asked themselves if what they were about to say would make sense to a mixed-gender audience. As I said, I'm not suggesting that there is any deliberate anti-male attitude, but rather that the assumption that every poster is female leads to a much more insidious exclusion.
(Oh - and I know all there is to know about badly fitting bras. My wife is disabled and has not been able to fasten her own bra for several years now. She recently lost a lot of weight using Slimming World (more than 5.5 stone) and so needs new clothes. And since I am the one who has to help her to try them on I have become quite an expert on the subject.)
