Hey rkgtech,
Thanks for posting! I’m afraid that the plugin only allows to be connecting with one MailChimp list at a time, so you wouldn’t be able to use the plugin solely to create signup forms for 2 different lists.
However, one option to consider would be to use the plugin for one list, then use an embed code for another. The embed code is provided inside of your MailChimp account for each of your lists that you create, so you should be able to grab the embed code for one of your lists, then paste then in as a widget onto any areas of your WordPress site. Keep in mind that you’ll need to use a version of the embed code with Javascript-disabled, as that can cause a conflict within the WordPress widget environment.
Another option you may consider (if you haven’t already) is to use hidden fields. Of course, this may not apply in all situations, but with the embed codes for your lists, you can manipulate the HTML code to create hidden group fields, which you can then edit yourself to “check” group options silently in the background. Depending on what signup form they use, your users could then be subscribed to certain groups in a single list. This way, you could manage a single list that DID utilize groups, but effectively hide the process of your subscribers having to actually check the group boxes. Each page would have its own pre-checked group field. However, this does require some familiarity with HTML form elements, so it would require a bit of code changing.
Let me know if you have any additional questions!
