Where can I submitt my 5 stars for your awesome Enfold theme?

I cannot find the option for submitting my rating on themeforest.net, despite being logged in.
Could you paste a link or direction?

For those you who already have used Enfold theme and experienced it’s next to none support team, I’d like to recommend submitting your own rating. This will increase the popularity of the theme and consequently allow the Kriesi team to invest more money and time in further development of the theme as well as maintaining the high level of support!

Question 2:
When Enfold parent theme indicates that there’s an update available, the child theme soon does the same – it suggests being updated, too. I did as requested and updated the child theme with the two last updates, and everything went well. The child theme seems to have a safety measure built-in, which prevented my quick css field from being erased. My child theme’s functions.php files had been populated with add_theme_support(‘avia_template_builder_custom_css’); but this didn’t get erased either.
The question is: should I update child theme at all when it prompts so ?

Thanks again!

Best regards,
