Thanks for your help so far! I am soaking up as much info as I can. Google is my friend.

I am already following a handful of very helpful blogs using google reader. Awesomeness.
I'm not feeling overwhelmed quite yet thankfully. I know it's a lot of info and people have varying opinions, but I love to see all the angles just in case one orchid likes such in such better than my other orchid.
Can you guys tell me what the icons are on the bottom right?
I see Like, Share (those are obvious) and then quote. Is quote how you would "reply" to someone's specific comment so they know what you're referring to?
What are the other two icon/symbol/pictures? Two pieces of paper and then paper and a pencil? Copy maybe, and....?
And should I sign with my real name/nick name like most of you seem to? I don't mind. It's not my SS# or anything. Is it just preference?
I'm used to things like Facebook, but new to forum type set ups.
Thanks!!
