The ADL has a page where you can "sign" a letter to the AUT asking that they revoke their boycott of Israeli Universities. I've generally felt that such things probably don't mean much signed by non-academics and non-UK'rs, but at this point I think it can't hurt to show how this decision has brought the AUT - an organization most people were never aware of before now - into international ill-repute.

Thereis an image of the letter here.

You can sign it here. It's quite easy.

Oh, and to show you the serious nature of some of the boycott's supporters, here's a link to a fun song you can sing to the tune of Bye Bye Love, as found on one of Sue Blackwell's web sites.
