Hey there,
I just tried to send a regional telegram to Warzone Sandbox, which I was under the impression I could do, due to having communications authority, but I could not send it due to having insufficient stamps. Now, it was no worries, since it was actually just a few people I was trying to contact, so I could just send them the telegrams individually, but I'd still like to make an inquiry as to this.
Now, I also tried to exclude some people from the regional telegram, so I wonder if this could be it. If this requires us to still use telegram stamps, then that's my bad, but I definitely believed that it didn't matter who we excluded, so long as we didn't include any extra people in the telegram.
Thanks!
