Featuring art on your profile page and in your journalIf you look around DA you'll see all sorts of different features on people's pages and in their journal - selections from people's recent favourites, thumbnails of work on a theme, collections of prints etc. This FAQ explains how to link to artists and their art in your journal, page and other places on the site: FAQ #81: How can I create links to other deviants, deviations, or websites?
While it's cool to be able to show off the work that you love in such a public way don't get carried away - when writing feature- or thumb-based journals, do your best to ensure that they have a theme and/or are informative. You may want to shine a spotlight on an artist you admire or a specific style of art, so use your imagination.
You could interview people and illustrate your article with examples of their work or you could put together an educational article using work from DA as examples of artistic techniques. The possibilities are endless, and there are thousands of existing journals to draw inspiration from.
You can browse journals on DA here.
Suggesting Daily DeviationsDaily Deviations are features selected by Community Volunteers and other staff members. One of the best things about DDs is that anyone can suggest work to be featured. Regardless of whether you're a member, a subscriber, a beta tester or a senior member YOU are welcome to suggest art that you love to the relevant Community Volunteers. Of course there's no guarantee that all suggestions will be featured, and all the CVs have their own guidelines which you should check out before sending suggestion notes.
You can find out which Community Volunteers feature from each gallery in this FAQ: FAQ #18: Who selects Daily Deviations and how are they chosen?
Sharing deviationsOn the right hand side of every deviation page (where the artist has sharing enabled), you'll see sharing buttons which will allow you to send a thumbnail of the deviation to someone else in a note, and (again, if the deviant has this setting enabled) display the deviation with a link to it's page and the artist's userpage on various social media platforms.
