I've not had any luck with U3A. Grrr! I emailed the local U3A to be put in touch with a particular group, but the person responded saying they were away and would reply soon. Fair enough. Nearly six weeks went by, I think they were busy or forgot, so I emailed again and was given details. I contacted the actual course organiser and received very clear strict rules about the group! 😲 I replied saying it sounded ideal, and could I join? No jolly reply!
Their loss! To be honest, I think many gransnetters on here would have been more welcoming. 
Sometimes, sorry to say, I understand why older people wouldn't survive long in the workforce.
A few years ago I emailed my local U3A membership chap, asking how I could pay the membership, as he was in one town, and all the groups I was interested in were in another town, so I wouldn't actually see him F3F. He replied, very curtly, that I should send a cheque! I told him that I didn't have a cheque book (I can't remember the last time I actually SAW a cheque book! Lol!), and was there any way of paying online, via PayPal, or something like that. He replied with just one word; "No". His curt, bordering on rude, manner totally put me off, so I never bothered after that. I have thought of looking into it again, to see if it's still the same chap, or if they've managed to move with the times with regards to online payments, but haven't got round to it yet...
