Hello colleagues!  My company's support area is in the process of implementing chat.  Can anyone share their experience or best practices to satisfy these criteria?  I'm specifically looking for Omni-Channel settings (queue or skill based), routing configuration recommendations, etc.

• Chat available on our authenticated Salesforce Community and/or public-facing website
• Automatic routing of chats to groups of individuals depending on a pre-chat form field (department)

I'm sure more requirements will surface but I'd like to start here.  Thank you!
