Sounds like you need a little isomorphic javascript in nodeBB. 😉
P.S., IMO the first-aid icon in the lower right corner of the compose window is confusing. I just clicked it and I still think it does something else. 😃
@tedr56 If you use one of the mail plugins such as mailgun you should be able to send everyone an email using the csv file generated by nodebb. This is done through a third party application as there is no way of emailing from NodeBB yet.
This could be a plugin, if you want to make it 😛
