Hi, I have a few comments. First, I like the idea of the forum. I do not go around searching for forums on a regular basis, but your idea seems to be a good one and not one that I recall seeing before. Here are more specifics:
1. In the Company Problems/Concerns section, I would add a category for 'Operations' and one for 'Management'. Both operations people and management people might have interest.
2. Note: I am a Sales/Marketing guy, so my comments on that section will be a bit more detailed:
a. Advertising should be a subsection of Marketing. As should Pricing, Promotion, PR, Lead Generation, Branding, Trade Shows, Direct Marketing, Telemarketing, Direct Mail, SEO, SEM, etc.
b. You may also want to break down Sales into a number of categories, including Outside Sales, Inside Sales, B2B Sales, B2C Sales, Overcoming Objections, Closing, etc.
Finally, I would consider ditching the MLM section un the Industry Connections section. It is tantamount to Techspot having a Hackers or Spammers section. MLM is as unsavory an industry as you can get and I would advise against promoting it in your forum.
