Internet feedback

Thanks for any fedback you can provide to help me keep the Internet advice here current and useful. I am especially interested in suggestions for weblinks that should be added or weblinks that I have referred to that should be removed or being informed about annotations that are problematic or defective in some way. I realise that such things are ultimately matters of opinion, and would be pleased to have your opinion. Please note that I am not keen on listing websites with direct commercial significance (such as those which require a subscription), although there may be good exceptions to this. Some websites are constructed mostly for teachers, instead of their students, while others may be suitable for both audiences; I would be pleased to be advised whether websites are misplaced here. My main focus is on freely available websites intended to be accessed directly by students and which you think are likely to be of help to students of mathematics in some way. (Websites aimed mostly at teachers are best placed in the Teaching collection.)

I have a suggested addition
