The beauty of this board is that it has been, so far, an open forum. Who, or what, was behind it has been transparent, (well maybe except for the time I got a "warning" from somebody for flaming at some poster who used a quote from Hitler.) Not to get too carried away, but there is something of a sense of 'community' here. There are some very knowledgeable people here, as well as those who post totally erroneous answers. There are the desperate university students who want someone to do their homework for them. There are the lazy engineers who can't be bothered doing an internet search themselves. But mostly there has been a very nice exchange of information. I have learned a lot just looking at other's posts, and I hope I've helped some people myself.
So, Marshall, don't mess it up!
I realize that this forum is now a business and you need to make a profit. Nobody here can complain about this, because we ALL want to make a profit. But, please, please, please don't sell our email addresses. Please don't spam my mailbox.
Here's a thought: charge a token 'membership' fee, like maybe $5 a year (nothing more). This is easily justified by any of the serious posters here, and it will keep those annoying PleaseSendMeaSchematicAndC-Code leeches away.
So, I'm keeping an open mind and waiting to see how this board evolves.
