Need some custom.css code make Change colors and boldness of "Please Login to view more feed items" in EasySocial Stream

On my home page at https://www.starch-smart.com I have placed the EasySocial Stream in my grid5 position that is titled Recent Social Activity. The text at the bottom of the page is getting lost. I am hoping somebody might be able to give me some css code that I could add to my custom.css file that would change the color of the font to Yellow and the color of on rollover color to white like I am doing with my menus. Or, if there is another nice way to make this prominent then I am all ears. I do not want this color change to effect other applications or positions. :-)
Thanks for any code you might suggest.
