I am unable to upload a custom image to my Boost page. I keep getting Bad Gateway
2. I would REALLY like to be able to add custom CSS + do basic design on the Boost page.
3. It would be EXTREMELY helpful to be able to add text to the boost page. For example, to get access to the PDF and to subscribe to our newsletter, click one of the following. Title would be helpful in addition to just a text block
4. On your site, it looked like you were able to ALSO include a html subscribe form on your boost page. Is this possible?
