First time novelist.

Hi Everyone.  Wow this is a fantastic site, and I've learned so much already!  I just had my first novel published, mystery& suspense,  and I wish I would have known about authors.com before I self published.  Although the agency I'm with seems to deliver what they promise, I still wonder if I should have tried traditional publishing.  Would value any insights from anyone who has had success in self publishing!  Thanks Vicki
