(Frenchy sorry) Hi =) I need to generate some crons via a form, if the form is posted at 19h49, the task must be executed every 20minutes from 19h49 and n times (n depends of a form field value). AND! It could happen that some forms posted by differents users generate the task at the same time with differents arguments(the user id). In this case i need to "verify" if an equivalent task is programmed before executing it, once. Is that possible?
