1. Probably the biggest of the four is http://forums.digitalpoint.com/. This website has everything to do with the Internet. It doesn't matter if you advertise or just like writing blogs, you can find every single bit of information there is to know on this website. There is even a nifty buy/trade forum where you can buy items/services or give them. It's free to join and it doesn't take long before you can post in every form. Just mind your P.'s and Q.'s and you won't get banned.

2. The next form is called www.blackhatworld.com. This forum mainly deals with black hat techniques, but that doesn't mean you still can't learn how to market correctly. Although a lot of these techniques are against the terms of services for a lot of marketing companies, you can still learn how to apply a lot of strategies the legal way. Probably the best aspect on this site is the member downloads section where you can get a lot of great software for free.

3. The third website to learn good marketing is www.warriorforum.com. This website has everything to do with Internet marketing and I personally have learned most of what I know from it. This is very similar to digital point, but it's solely focuses on Internet marketing. To be fair, most people don't know what they are talking about. If I were to learn something it would be from the moderators as they are hand selected by the site owner who does know a thing or two about Internet marketing. You can usually tell though which information is garbage.

4. The last website to teach you good marketing is www.wickedfire.com. This is a much smaller forum, but it still has plenty of information you can use. You will find that closer communities have less rules and restrictions about what you can post and I prefer that.

With these four separate forums, you will have more than enough information to start doing proper marketing. Just make sure you make some color copies of the information on these websites so you can sit down and read them in your spare time.
