Calling out people

Since, i have been very busy lately. getting absolutely not time to post new puzzles or respond to people. I would want someone serious, to contribute to the blog. If not actively, passive help is more than welcome. If you come across new puzzles or anything related.. Please do contribute to the blog.

Thanks,
Sunil Kumar

Rumour-mongers Puzzle

Rumour-mongers Puzzle

You surely need me to make a point sound
I could save time or ease your workday
Rumour-mongers in the market pass me around
When you are satisfied you give me away.

What am I?
