For a Westmarches game, we handle applications through PMs that are supposed to be sent to me. We have now had several people remark that they get the following message when attempting to do so. This problem seemed to persist on both Chrome and Firefox. Another person I do share games with tried, and could get through, so it's probably not on my end, but since it's been at least three people now from different countries, I figured I should ask here. (And of course, it might not have worked for more people.) I haven't changed anything in my settings, and it seems to be a recent problem, and I am not sure how to fix it. To troubleshoot, the last person also tried to send messages to other people with the same result, and even made new accounts, again with the same result, and tried it from a different computer too.
