Another consideration to think about is whether you want your online training to be available publicly or privately. For example, is it training that is specific to your organization, your members, or to a broader audience? Do you want people to simply be able to go to your training site and have full access or do you want more control over who is seeing your training content? Or, is your training an accredited course from a college or university where only registered participants would have access?
If you want to make your training publicly available, you may still also want people to register so you can track detailed user statistics. However, if you are required to approve everyone who wants to register, this will require some staff time. Be sure that your organization has the ability to keep up with requests if you choose this option. You can also make your training publicly accessible with no registration requirements. Many self-study modular training websites are set up in this way, i.e. anyone can freely go to a website and work their way through the training content. If you choose this option, however, you should note that all of your content will be available to anyone who finds their way to your website, and regardless of any copyright notices you might put on that content, others may use it for their own purposes.
If your training is open to the public, you will want to think about how to effectively market it to attract participants. You can create flyers, post notices on your website, send e-mails or post notices in newsletters. Identify your target market and get the word out!
