Not from me. You can't argue with some person who is willing to work for free. I used to underprice my work when I was a newbie. Didn't value my work at first.
Now my work has worth, and in all my years in this game, I've learned that people only value your service if you value it yourself. So working for free is de-valuing yourself.
People who do that are selling themselves short and lie to themselves by telling everyone that it's a little bonus for their customers or some such dross.
The truth is, if they had enough work, they wouldn't havre time to do free stuff for custies. But you find these are the same people who tell the world about what little problems they have with poor payesr or moaning custies etc. Then they boast about how well it's all going and they're about to buy out the nearest four or five firms in the area and employ an army. All so they can continue to offer free work.
Blah blah blah. The emptiest vessel makes the loudest noise. Bragging and spouting about how good you are can be smelled from 5 miles. Telling everyone how great you are and that you work for free is amusing.
It's only a forum mate, and you can spout all you want. Someone will be impressed, but it won't be me or your bank manager.
HTH.
