Thank you very much for your help. As a follow up, I also noticed that the form fields for name and email on the my guest post submission page were still there after removing the code that cartpauj told me to remove. To remove those form fields, you have to go to the "ucan-submission-form.php" file and either remove or comment out the following lines:
<?php echo __('Name', 'ucan-post'); ?>:
<span class="small"><?php echo __('(required - not shown publically)', 'ucan-post'); ?></span>
</label>
<input type="text" name="ucan_submission_guest_name" value="<?php echo stripslashes($_POST['ucan_submission_guest_name']); ?>" />
<label>
<?php echo __('Email', 'ucan-post'); ?>:
<span class="small"><?php echo __('(required - not shown publically)', 'ucan-post'); ?></span>
</label>
<input type="text" name="ucan_submission_guest_email" value="<?php echo stripslashes($_POST['ucan_submission_guest_email']); ?>" />
I hope this helps anyone out to achieve the same thing that I was, and thanks again cartpauj for your speedy help!
