open stacks gallery updates

[Marielle Lange]

The open stacks gallery has been updated with nice stacks spotted on  
revOnline.
<http://revolution.widged.com/stacks/>

If you would like your work to be shown there, simply send me an  
email with information about your stack. Your stack don't need to be  
on revOnline for me to link to it. It can be on your own website or I  
happily host a local copy of it.

Best,
Marielle

PS. if at any point you would like me to stop linking to one of your  
stack, let me know as well.
