Thanks SH3
anotherworld -at- jagware -dot- org is an email adress directly redirected to SebRmv (Who made the portage) and the RGC team. You can write in english, that's not a problem be sure
This email adress has been created because the RGC team has changed several times of email adress and when we tried to contact them, you got an non delivery error.
That's why this email adress exist even if the RGC team change their email adress, Seb got a copy of the email so nobody will be forgot.
