Everything on Renshuu is customizable to the pace and content that you learn best with; it's not force-fed to you, you control how long you grind on the syllabaries and when you move on and to what. If you've finished being introduced to all of the hiragana and katakana so far, you should have gotten a message in your inbox suggesting you continue with Japanese Basics, but you can either do that or study with whatever other material you want.
On your dashboard, click "manage your schedules" to see your options for adding Renshuu's curriculum (Japanese Basics, which you can also review in the menu) or schedules based on whatever textbook you're studying with, or you can create an empty schedule to fill with any lessons that interest you or you create in the Lesson Centre (also in the menu). The pace of learning and how much you review a day and what type of questions you're asked are all changeable using the settings gear next to the schedule.
