so when you say it will not support services like SendGrid, does that include configuring the forums to work with Gmail?

what is local send mail? I don't see where that can be configured

On my local installation, drag and drop doesn't work for image upload. When I used Chrome to "inspect element" the source code, I saw a "imagedrop" class, however, when I put my curser on the element, it didn't highlight where the image drop was in the composer box. Normally when you do put your cursor over an element in the Chrome console, it does highlight where that element exists on the page, so I'm assuming it doesn't exist on my installation for some reason. Do I have to activate it somehow?

Looking at the codebase, it seems like NodeBB should be able to send emails to users, but I can't find where I'm supposed to put the information about the email address it should be using. Does anyone know where I should put this information and what information I will need exactly?
