If you want to show events on your website only you should enter the details into the Website Events Page.
If you have an account in the AccuBook Media Centre, you can publish your entertainment and events into the media centre. This information will then be shown on your own website as well as all other sites linked to the AccuBook Media Centre ( such as donegaldirect.com, donegaltown.ie, discoverbundoran.com etc )
Some sites filter the information they show based on geographical location so your information will be shown on any sites accepting information information for your area.
