Razza the EHM tours are easy to figure out how to report ;-), Andreas wants to know about the IFR World Tour that IVAO released on January 1st (I think), and as far as those go, I think Karsten is right, you can't post them on the page as they are not part of the schedule. However about using the EHM callsign you can use it as much as you want for just about whatever you want, actually the more you use it the better:-)
Cheers,
