Hi,
MapPress doesn’t provide a front-end form for entering data – maps can only be created through the admin screens (i.e. the WordPress post editor).
However, there are some forms plugins that will take front-end user input and generate a post from it. If you choose to use one of those, you can store the address data in a custom field and have MapPress generate the map automatically from that field when the post is created.
I hope that helps…
