In your documentations, you compare Licence Editions, like this

                                                         Anonymous  Community         Unrestricted
Processing Threads                                     1                      2            int.MaxValue
Max Working Tasks                                        2                      20         int.MaxValue
Max Tasks per Minute                                    60                    600       int.MaxValue
Max Tasks per Minute Check Interval (s)   60                    120       TimeSpan.MaxValue

I have Community licence, How can I change this parameters?
I want to limit the number of concurrent tasks. How can do this? For example only 5 tasks max. in parallel
Perhaps one solution is to use QuotaLimiter?

Thank for your help.
