A quick clarification, for others who might have the same question. You'll keep your MozPoints, but only have access to Q&A if you have over 500 MozPoints or have a paid account. Karl, you've got well over 500 MozPoints, so you'll still be able to use Q&A.

I believe newspapers use a feature called "first click free" that enables this to work. I don't know if that will work with your industry regulations or not, however. You may also want to see how sites that deal with adult content, such as liquor sites, have a restriction for viewing let allow indexing.

Use any plugin and notice that external links are nofollowed.

Moz has recently had a little bit of experience with a rebrand, changing domains, changing URLs, implementing redirects, and a variety of other fun things to keep us busy. Ruth Burr, our in-house SEO, is giving a Mozinar that talks in-depth about this migration on Thursday, with a chance for you to ask questions at the end. If you're not able to attend the webinar, we'll have it online for download within two days.

I think of it as why did my mom tell me I couldn't go to the mall when my dad told me I could. Same question, asked of two people with the same goal (to parent their child), yet Mom took into account that I had been playing video games instead of doing homework, while Dad took into account that I had cleaned my room the previous weekend.

The two engines have different indexes and different factors they look for in ranking things. I'd be sure to check in Google Webmaster Tools to see if there are any notices to you there. Also look at who is ranking above you on Google and see if there's a reason you should be above them (do you have higher-quality content? more links? etc).
