I came across a nifty trick to subscribe to the openmod mailing list, because I do not have a google account, nor do I wish to create one. To subscribe to any google group with your regular e-mail address adapt the following URL:
replace "email@example.com" with your e-mail address, open the URL in your browser and you’re presented with a dialogue to subscribe to the list. Hope this is of help to anyone and a good location to share it.
(Replace openmod-initiative with the name of any other google group to subscribe to)
