@Lorna170 Hi, and thank you for what you wrote/advised.
What I should have said - but failed to - was that I mostly use my mobile phone to access the Community Center - and then primarily because I'm usually out and about every day. I also don't reply to every new topic, but only where I think my comments might help others (I do read all of the new topics sent to me via email, although most don't have relevance to what I've encountered to date). I apologise therefore for not having considered that you might not be accessing your Airbnb account via a mobile device (that's a lesson I've learned today, so many thanks for indirectly pointing that out to me).
I also accept your comments as to not clicking on an email or text link, and I know of many who won't and never will click on any links, but then I too will never click on links when I don't know anything about the sender.
Keeping safe whilst online should be everyone's concern, so that you have a policy that works for you - and also that you had retained the link to the Community Center so were able to access the page are both to your credit.
The one thing that seems to have emanated from all the replies to your original question, however, is that not all of us use the same method of reaching this page, yet whichever the route each of us takes, that we get here is the main thing!
