Tighten Up "Top News/Everything" Header Area:

If you have activated the "Top News" Tab under your Activity Feed (My Network/Settings/Ning Labs/Top News), you may find as I did, there's a little too much margin space between the title: Top News/Everything and the Feed below it. And, the font could be larger to make this option stand out more.

Instructions:

• Edit the code below, changing to your preferred font size and margins. The margin-top:5px may be too tight for some sites.
• Add to your Advanced CSS via: My Network/Settings/Appearance/Advanced
• Save.
  

/* Tighten up Top News/Everything */
#xg_network_activity .activity-feed-view-selector {
    font-size:16px;margin-top:5px;margin-bottom:0px;
}
#xg_network_activity .activity-feed-view-selector:before {
    content: "» ";}

I made the font larger, narrowed the margin top/bottom, and added my site's signature arrow (hex character) before the title. Feel free to do the same.

Hope this helps someone else.

Enjoy,

Jen
