Add links to check mark boxes and using them for sign ups.

And it would be really awesome if one could make multiple opt ins on the email sign.

I.e. sign up for newsletters, Send me promotional materials and sales events, etc.

Most of the better email services allow for such segmentation.

It would be great if we could add links to specific words for check mark boxes in custom fields. Especially for the sign up form.

This is possible, just add the < a > tag with the href attribute and it'll work fine. The example is shown on the screenshot: 

Second suggestion. Be able to integrate newsletter sign up (as shown at the bottom) with the most popular providers. Even if this is another paid ad on, it would be worth it.

Currently, we have plugin customization and custom addon development services at the gVectors Team. They can asses the work and create it for you. Just contact us via sales[at]gvectors.com email address and send a list of requirements you'd like to have.
