Well, we have 27 signups. The super special is first, so there should be 2 people going off every 2 mins. In the rest of the stages, a car goes off every minute.
So for the first person, it'll be: total time to drive each stage (<10mins) + time moving between servers (<5mins). For each person after that, it'll be a case of adding the additional time waiting for the gap between each person. Say you're 10th in line, that'll be the 5th SS1 race, so a ~10 min wait. So basically, it depends on how many people turn up, but I wouldn't think it'd take more than a hour or so.
2. Entries close when the rally starts, as I need to get you the password and after that I won't really check the forum.
3. Whatever, only the username is required to track you in the rally
