Tags for FYI & Forwarding

1. ".fyi2-fwd2"
• FYI normally means "for your information".  But we may extend to "interest" and "inspiration" as well.
• FWD is abbreviation of "forward", as traditionally seen from AV-device's panel.  Also "F-FWD" was considered because by nature we usually do fast-forwarding (i.e., don't think much and just forward)
2. "+2" can be symbolized label of "fyi2-fwd2".
• It means "adding (sharing) to others too" in comparison with term "+1" in social networking language that means "add me as another one vote/voice/count": i.e., "me too".
• "+2 xxx" (where xxx denotes additional sub-keyword) to optionally specify some keyword if we want to implement several topic groups.  Then this label can be said "add to xxx too".
