Hello,

You should be able to copy contact form folder to rsvp-form but you will need to change function names also (next to the paths you already renamed). For example, all functions in contact form plugin start with "iucontactf_"

So there are several functions but one of them is iucontactf_display_form (used to change IU conent on-the-fly just before it is displayed to the user and to replace [contact-form] tag with actual form). You should replace it with e.g. rsvpf_display_form, and also, at the end of contactform.plugin.php (which would be rsvpform.plugin.php in your case) there is a hook for content:
add_hook('content','iucontactf_display_form');

You should change it to:
add_hook('content','rsvpf_display_form');
(as well as all function names, of course)

Also, there are some JavaScript functions (file contact-form.js.php) which start with "cform_" - you should rename those too (and their calls in the code) as neither PHP nor JS allow two functions with same name to exist at the same time.
