Did your post have links in it? I’ve actually responded to you in another thread today, re calendars etc, and something weird happened – it didn’t post, but when I tried to repost, it came up as a double post! I removed the links and then it posted fine. This happened a while back when I posted with links. Perhaps the system has an anti-spam filter or something.
On my profile, there is a red “remove” button next to the avatar.
