Can I redirect new users to Memberships page instead of having them activate?

I currently have a call to action button called JOIN NOW that sends users to the Memberships page. If they have never logged in before, it sends them to Register instead (which is good.) After they create an account though, the page message displayed says" Check Your Email To Activate Your Account! You have successfully created your account! Please log in using the username and password you have just created."

1. No email seems to be sent. I would like to change that message so that it does not say to check their email.

2. I do not want to hassle with having the users activate their account.

3. Biggest Question here....if they do log in using the newly created username, it takes them to the home page. Is there a way to have it take them to the Memberships page instead?

Thanks for your help! -Barb
