As Oli says, if they're otherwise good questions, at this point we can allow them.
However, keep in mind that, especially near the end of the beta when many people are installing it for the first time, many 13.04 questions posted recently are bug reports.
So every time you see a 13.04 question (especially in a close or reopen review queue), ask yourself if it's really a bug report. Many of these questions are outright crashes, or ask about strange behavior just after a crash. Some bug questions are more subtle; generally, a question that asks about strange behavior that's definitely wrong and unlikely to be a result of wrong configuration should be considered a bug report and closed (with helpful comments to explain to the OP what to do).
