Considering your reputation, there's effectively no limit to the number of questions you are allowed to ask per day. This information comes from the Complete Rate Limiting guide on Meta Stack Exchange.
- Users with < 125 rep, 40 minutes since their last question anywhere on the network
- Users limited by Anti-Recidivism System, one question per week
- Users limited from asking questions for 1 – 7 days based on the performance of their previous questions
- Users with < 10k rep trip Captcha if more than once per 60 seconds
- Users with > 10k rep trip Captcha if more than once per 30 seconds
Please do take the time regardless of this to make certain your questions are of good quality and well-researched. Too many low-quality questions may not cause you to be blocked from asking but they may cause annoyance. So, ask away!
