1. Do you have to start the rally at a specific time or is there a window to race within? .
Using RSRBR2010 for our on-line Rally Events, we set up Rallys to start at a specific time. However, we try to be as flexible as possible by setting up the Rallys to begin at different timezones. eg. We always have European Rally's starting at 20.00GMT Monday, USA is 3.00GMT, and Oceania at 9.30 GMT Tuesday. We then, often, set up additional rally Start times on Monday / Tuesday to suit specific requests if those times don't suit someone. We try to be as flexible as possible, however, it usually best if most drivers run the same Rally (Start Time) because then they get to see how they are progressing compared to others in that rally. The more drivers you see in your on-line session, the more enjoyable it can be.
2. Do you have to finish by a specific time?
In each Rally, you must start at the set time, but you are then allowed a set time to complete each Stage. If you finish the Stage early (which is usually the case) then you can continue to the next Stage immediately, or wait till the set start time for the next Stage, or anywhere in between. So, depending on when you start and finish each Stage, you can vary how long the whole Rally will take. If you don't finish a Stage within the allowed time (which is quite generous), you are given a default penalty time for that Stage.
3. Do you have to run the stages one after the other in succession, or can you take a break in between?
As described above, it is fairly flexible. yes you can take a break between Stages, but you need to be careful to return before the default start time for the next Stage. If you miss it, you can run the following Stage, but will receive a penalty time for the missed stage.
I hope this helps, it is not easy to explain it in very simple terms, but it is quite flexible.
We have a basic Tutorial for RSRBR2010 which may also help:

The best way to get familiar with it is to just join one of our Rally Club Events, hop on teamspeak if possible, and ask more questions if needed.
Please feel free to ask again if it is still not clear, and we'd love to have you join us any time.
EDIT: Aaron posted at the same time as me, fortunately we both said the same thing, lool.
