So with v3 the first thing rolled out was clean profile URLs, so that you can link people to your profile here easily:
http://aethercards.com/discourse/profile/USERNAMENow you can do so much more. The limits are endless, and I'd be curious to see who can use the new profile to the maximum output.
To edit your new profile, go to Profile -> Modify Profile -> Ultimate Profile
Then, begin editing!
I'll list the new things you can add below:
Buddy list: You can add friends to your list, just visit their profile and look under "Contact Me." You can also edit your profile so that buddies gain certain permissions in your profile that other users don't have!
Commenting: You can leave any comments you want on profiles now! This is especially awesome for leaving feedback for trading partners and such, or just saying hello.
Picture Gallery: You can upload your photos and images straight to the site, just go to your profile summary, click "Pictures" and click "Add Picture."
About Me: Share your bio with the world!
Media Gallery: You can embed literally anything in here, try it! Use HTML to make your media gallery sexy. Have videos to share? Artwork? You can put them in this section and create your own public media gallery.
Profile Customization: You can use HTML and CSS to give your profile a unique look.
As time goes on, I will be changing the graphics and display styles on the profile pages to make them look even sleeker.
Coming next: Embedding videos into your posts... from any video site, not just YouTube.
