Performing various tasks on the site on the Opencart platform

For a tdom.info site on the opencart platform, you need to:

1. Set up the sending of data from the completed form from the section "Exchange and return of goods"
2. Bring the fonts of the site to a single style
3. Fix the registration. When a person introduced the first 8, it was not taken into account (or even remove 7).
It is necessary that when skipping any point it gives an error that not all the fields are filled, and does not throw out as it is now.

There are still tasks on the site and periodically accumulate new ones, if you successfully cope with the above described, we hope for long-term cooperation.
