Adding the ApricotMaps directory to WordPress requires the ability to insert an iframe. This may require you to install a plugin. Since every WordPress setup varies differently, the best route to take is to ask your website administrator or webmaster to insert the directory for you.
To embed the directory, they will need the embed code - this can be found when you log into either apricotmaps.com or dashboard.wildapricot.com. Click here for more information.
Depending on the WordPress setup, they would either insert this code directly, or extract your unique URL from the code to use with a plugin that will create and insert the iframe.
