The biggest mistake on most artist websites is not providing a way for the visitor to sign up for a newsletter.
When artists cancel their FASOaccount, I send each artist a personal email asking for the address of their new web site. You see, I collect art and I want to be able to keep up with many of these artists.
Many of the artists who respond tell me they love FASO and don't have a new website. The ones who respond this way are usually simply focusing on other areas of life and have decided to forego an art website for the time being.
It humbles me they take the time to assure me that, when they put their art back online, they'll return to FASO.
Others, who are still actively showing art online, but have decided FASO is not for them, often do respond with a URL to their new website address. And when I visit those sites, the first thing I look for is a way to subscribe to a newsletter.
