<p class="MsoNormal">Hi, I have Mailchimp for WordPress installed for integrating with Mailchimp. I have enabled an option on BudddPress registration page to allow user to subscribe to the mail list.</p>
<p class="MsoNormal">Subscription works fine. The only thing is I want <b>Name</b> field on the registration form to map with the custom name “<b>Full Name</b>”of the mailing list of Mailchimp.</p>

<p class="MsoNormal">How can I do this?</p>
Well I guess this query should be redirected to the third party plugin tat you are using .
Coz we have not used mailchimp for wordpress plugin,so please try contacting third party plugin author or support on this .
