Editing domainchecker widget

[cek3]

Hello community!

 

I added the domainchecker widget to my template and it is working fine.

But now I have to questions about it.

 

1) Is there a way to add a captcha check to this widget like in the normal domaincheck?

2) How to change the given select box in many checkboxes, so that a user can choose more than one domain for checking?

 

Thanks in advance!
