People will one day be able to post on forums not only for fun but also to make money. It's good for both the people who post on the forum and the people who hire them. Paid forum posting isn't a new thing, but it hasn't really taken off the way I think it will someday. Many people who post on forums are loyal to their own forums and only post there because they like the community and the quality of the people who post there. But if these forum posters knew how much money their hard work was making for the forum owners, they might think they should get some of this money. As any webmaster knows, it's not easy to come up with new, unique content for a website all the time. It is hard to be both a technical expert and a prolific writer.
Jobs and trades that are posted on a forum are best done in the open, right on the forum. There are a lot of places like this where people can talk now. It's getting easier and more common to find forum posters who are willing to post on forums in exchange for links, hosting, or even just cold hard cash. This is something good. Forums are one of the best ways for authors and readers to meet and share information in a way that has never been done before. It's one thing to read a person's opinion in a newspaper or magazine and then send a letter to the author. It's a whole different thing to talk with the author in a forum that's close to real time.
So, if you have a forum that is just sitting there and not being used, think about exchanging posts with other people as a way to get your forum to a point where it has good content and is appealing, so that other people will join and help you build your community. Or, if you have more money than time, offer to pay someone to post on your forum. You'll be surprised at how eager some forum users are to post in your forum for pennies. Of course, the better the content and English Grammar on your forum will be, the more incentives you can give to forum posters. If you try to lowball them, don't expect them to go out of their way to help you. You want to get to know your forum poster so that if you need him or her to come back later when activity is low, they will be excited for your next forum posting job.
