Sometimes they come out of the blue from someone or something you did months or even years ago. 

As do artists and blue collar workers.  

Blue collar or white collar?

You'll find lots of useful info and make great connections here on BP.I work for a development company, Blue Sky Homes.

As a realtor, I was a pleasantly surprised.... a past client (landlord) called me .....out of the blue, he told me to please help him list..... as I started planning out marketing strategy....

If you select it then the whole name will appear in the post in blue and now you have mentioned that person and helped them increase their Profile number.

once you choose the person from that prompt it will turn the persons name blue and will send tgem a notification that they were tagged. 

Do they view contractors as simply blue collar folks or businesspersons?  

I don't know how much longer it will stay like this - but it is an old blue collar town - very close to downtown Portland, but on the east side (Downtown is on the West side).  

Blue collar workers and lower-middle-class tenants pay lower rents here.D = war zone.
