Try again: Ok, something is stripping URLs out of emails. I just sent that URL to myself and it wasn't stripped so it's not my mail infrastructure that is doing it. Did someone "upgrade" the spam filters on oss.sgi.com or the barracuda overnight? The link - minus the "http://" bit is: oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs-2.6.git;a=commit;h=8c6266658cb76e282c14cb92f8ba5a1c674f4928 let's see if that gets stripped....
