I am playing in two prediction communities and I don't want to copy all my predictions from one community to the other one.
On the page My profile/Copy predictions, you have all the options to save your predictions to other communities.
Please note that the copy may not work if different rules are applied. For instance, the lead time could have already expired in the other one or there is a strategy prohibition. In this case, it is impossible to copy your predictions.
Always take a look at the "prediction bell" on the upper right-hand side corner. It shows you the upcoming and not yet made predictions for the next 24 hours.
