 * Anyone else having problems with this.
 * I’m using clientAPI and listID I find in the URL. Seams simple enough.
 * Am I missing something?

 * Hi dDon, good question, indeed it is not very clear.
 * 1) For the list ID go to List & Subscribers, select the list you want. On the
   top part of this page, click the link “change name/type”.
 * Or, construct an url like this:
    `https://[accountname].createsend.com/subscribers/
   createList.aspx?listID=[short list ID]&action=edit`
 * You will find the list ID for the API, it is a 32 character hexadecimal string.
 * 2) You can find the api key by clicking “Account Settings”at the top of the page.
 * Or, construct an url like this:
    `https://[accountname].createsend.com/admin/
   account/`
 * In both cases, click “show API Key” to reveal the key. It is also a 32 character
   hexadecimal string.

 * Found it 😉 of course I missed the correct ID.
 * My bad, but still, I’d rename it to “API Subscriber List ID”.
 * Thanks Carlo. Very simple and to-the-point plugin.
 * Couple of questions:
    1. does it update (not add or ignore) on sync? 2. does 
   it auto sync all or just “send” newly created?

 * Hi dDon,
 * I changed the description so it reflects better what the plugin does exactly.

 * We created another plugin campaign-monitor-dual-registration that does NOT remove
   users from Campaign Monitor. Please have a try and let me know if it works for
   you.
