Topic: Posting art for the first time

So basically I've been trying out furry art for a while and was considering uploading one or two to test the waters. Just wanted an idea from people, is uploading to e621 exclusively advised/not advised? Any traps I need to be aware of? Is watermarking/artist protection a problem? Do I tag myself as the artist? (I know it sounds obvious but it feels weird, humble brit is humble)

Basically it's a big ocean and I want a little coaching before I jump in so I don't make a rookie mistake or upset anyone, thanks.
