Every Wild Apricot website shows "Powered by..." branding below the site footer:
We would really appreciate if you could keep it as is – these links are helping us to spread the word and get new potential customers (which in its turns helps us to grow and invest more and more into ongoing product development, benefiting all of our clients).
If you really have to hide it, you can contact Wild Apricot support and ask them to switch off Wild Apricot branding.
This option is only available for paid accounts.
Do not use CSS code to hide this branding. This approach makes your site look like spam since our branding and links will still be visible to search engine crawlers, resulting in possible penalties to your site and ours.
