I'll start this off straight, I'm an intern who got way too in over his head. I am tasked with migrating our SharePoint 2010 environment to 2013. But in doing this I need to edit some of the social features. Currently, I need to turn off the ability to "Share with Everyone" in the microblogging web part. This is what I mean:
I need to remove the "Everyone" option from both areas highlighted, but we have done so much custom development and my permissions are so restricted I can't edit the sites half of the time. If someone could give me the files that the corresponding CSS definition is in that would be great. I've been programming for years and including Web Design and UX, but I really am in over my head here, SharePoint Designer 2013 is nothing like Dreamweaver which is what they told me.
