Make it easier to promote your groups with Vanity URLs. We've supported this a while, but they had to be manually created upon request. Now, you can create URLs yourself. Soon we'll be offering this ability for profiles as well.
To create a Vanity URL for a group you manage, go to settings on the menu panel on the right. Then click on the URL panel to expand. Enter your proposed URL and click update. We'll let you know if it's available.
Once you're done, you'll have a URL like this to promote your group.
