I have two slightly competing goals for my forum:
I’d like to keep it open, so that it can be crawled by Google and I can benefit from SEO.
However, I’d like to get emails from users via signups, so I’d like to get a link to get them to signup.
Ideally, I could set the homepage of my forum to be a signup page, but if you have the URL to a thread or if you search on Google, you could still view the conversations.
Is there a good way for me to do this?
