In the Server field of the Winds tab, we just had to enter <race>.virtualregatta.com
[edit 1] This is no longer true, since VR changed the names of the winds directory.
But, as everyone may know, MP's forecasts suffer several drawbacks, they are somewhat time-shifted and are not updated regularly.
So, I set up my own winds server and I bring it to you now.
On this server, updates are performed 4 times a day, taking data directly from the NOAA servers.
These updates are performed 4:30 after the hours of reference of those files. i.e. 0h, 6h, 12h and 18h GMT.
So, this makes 4:30, 10:30, 16:30 and 22:30 GMT.
Or, in French Winter hours: 5:30, 11:30, 17:30 and 23:30.
And soon, because we're changing time next sunday, it will be 6:30, 12:30, 18:30 and 0:30.
For those accustomed to zezo, it is just half an hour before its own updates.
Paco (from PACOTOOL) was kind enough to make me a little room on his server which is more reliable and powerful than mine:
Thanks a lot to him, and please remember to click on his "Donate" button.

So, now, the address to enter in our favorite tool is : vrtoutoulz.fr/winds.
Do not put any http:// at the beginning, or it wouldn't work.
[edit 2] I changed the above address to make it link to our brand new server.
[edit 3] You may consider, adding the race name as follow : vrtoutoul.fr/velux/winds for instance. This information is not used yet, but may be one day.
Enjoy it!

Ricoo.
