The provider for screenshots on MathsLinks has been updating meaning that all sites now have a nice, slightly larger preview image. For YouTube videos, I’m getting a screenshot straight from the video.

Any link on MathsLinks can be “liked”. If you find a link useful, like it… just click the thumbs up. This lets teachers quickly judge if others have found a link useful.

As always, your feedback is welcome.

Oh, and MathsSearch is back and working properly. MathsSearch uses a custom Google search to search over 150 maths related sites.
