I logged in on my tablet, typed a message, went to post and a little red notice came up saying something like 'you need to log in to post', I can't remember exactly because I gave in after it happened several times.
If you have ticked a choice somewhere on your PC or tablet (maybe phone too, I've not tried that) to delete cookies every time you close it down, then you will have to log in afresh when you start it up again. However, I don't understand the logging in to post each message.
I am having a problem posting messages. I am logged in but a message comes up to sign in before sending messages. I have to log out and sign in again for every message I want to send. Can anyone make a suggestion as to what is happening.
