I have a lot of text like this in Notepad ++:
User Actions
Follow

Talk about #socialmedia, #SEO, online marketing, affiliate sales, #SMO, #PPC and much more. Join the discussion.
User Actions
Following
Mashable Verified account
@mashable

I would like to extract all twitter handles - get a unique list like this:
@mashable
@LookSocialMedia
all Twitter user profiles in one list.
What is the best way to extract those usernames and have unique list of them in one doc?
