I have asked some running related questions on Fitness&Nutrition. How can I migrate them to Sports (probably only when the public beta starts)?
Running is on topic on both sites and should remain as such. However running questions here should be directed towards competitive running (I don't care how F&N chooses to define their scope on running questions or whether there is overlap). However this is not the place for recreational running.
A moderator will have to migrate the questions from Fitness to Sports. You currently have two questions on Fitness (both related to running), but the "running" tag is also the largest tag on Fitness with 179 questions total.
There isn't a need to migrate any questions especially when Sports is (currently) in private beta and the scope and faq haven't been fully determined yet. As it stands right now, all the running questions are on-topic for Fitness.
