I know there are Rosalyn, so I read, but I steer well clear. Why would I subject myself to that upset?
It's not an excuse, but I suspect that some posters are very angry with life and take the opportunity to lash out and hurt people under the cloak of anonymity.
On the other hand, there are some very kind people on here, it just takes time to find them.
I hope you do try again.
You are very welcome on Miss MaryDoll's Maths Class.
It's not really about showing off maths skills, it's about communicating with others. You won't find any nasties on there, they are a lovely, if unruly lot!
You don't even need to answer the questions, if you don't want to, just join in the chat. That's if you can understand it, I can't!!! ?
