as there were only very few registrations for the last tournaments, the Tour Mods didn't feel like making the Tour go on like this.
So the TE Tour will go on stand-by for a little while, with only opening registration for big tournaments (ie: Masters 1000 & Grand Slams).
Hopefully, the Tour will get bigger when we can switch it to TE4. This should arrive when the TE4 demo is available, and if there's no obvious game exploit to fix, so at best a bit before Roland Garros and at worst hopefully a bit after Wimbledon.
Note : TE4 gameplay will evolve over the months, so the Tour will likely be bumpy for a while...
