There are many online classified sites. A lot of them offer free sign-ups and the opportunity to upgrade to a comparatively inexpensive monthly membership if you want to create more sophisticated ads than what the free service will allow you to do. When you join a safelist, you can send out promotional emails to the other members of the safelist. How many e-mails you are permitted to send out depends on how many emails you read, because other members are also sending you emails. With safelists you also have the opportunity to upgrade so you can send emails without clicking to earn credits.
Traffic exchanges work in a similar way. You earn credits by taking a look at other people’s advertisements and, in turn, you can place your advertisement for others to see. Like with safelists, you can upgrade and opt to pay instead of spend some time clicking for credits. Forums and social network sites are simply free and represent an online method of networking. To be valuable in this area, you definitely need to keep things social. You should not be doing any direct overly promotional advertising. Just let people know that you are out there and what you do.
