When Google Plussing ... (is there such a term? Oh, well, there is now!), don't forget that there is a Google+ Help section, close at hand!
For instance, when you want to add style to a Stream Post ...
- Use underscores to italicize. _ italics_ → italics
- Use asterisks to embolden. * bold* → bold
- Use hyphens to strikethrough. -strikethrough - → strikethrough
- Use + or @ to link to someone's profile... eg: +Natalie Villalobos
Plus 'heaps' more!
