Grey Goose is aware of the issues with chat, and is investigating to find the cause.
Regarding the screen shot...as long as I have been a member that feature has not worked. There are other ways to take screenshots depending on the device being used. I almost exclusively use my IPad. To take a screenshot, I hold down the home button simultaneously with the camera button. This will take a pic of the screen and put it into my camera roll.
I believe Cuchculan has replied to this post with instructions for taking a screenshot on a computer.
As far as religion and politics, I personally am not opposed to a discussion, as long as no one gets offended and there is no conflict. But these conversations must be monitored very closely, and if there are many conversations going on in chat, it can be hard to keep up with. So, I understand stopping these conversations from the beginning.
I hope this has answered some of your questions, Pink!
