Has the computer world gone mad?

I just did a lengthy post with pictures and links. Then when I clicked on 'Publish Post' it said 'you must sign in before proceeding...' and I lost everything. GRR!!!! Then, when I go to Crochetville and log in, it takes me directly back to the log in page... What the heck is going on?? Maybe I'll just go crochet. As far as I know nothings changed with that...
