RE: [eigen] lowest eigen value only

Agreed. 

 

Open source is not just about great code, it’s about being a community, and a fundamental community principle is bulk mailing etiquette, one key tenet of which is to have a clear “unsubscribe” button at the bottom of every mail. 

 

That button should not just be a generic link, it should contain the address to which the mail was sent, so that auto-forwarded mail can be traced.

 

So this mail should have arrived to me with a footer containing a link something like

You don't often get email from costagol@xxxxxxxxx. Learn why this is important

Hi Guys, 

 

Can someone please remove me from this mailing list?.. I tried to do it myself following instructions available but clearly it's not working. There were already other emails about emphasizing how important is to take this seriously. 

 

Thanks in advance, 

Sebastian

any news on this?
