I am not listed as a member, although I have made 2 posts. Anyone know of an explanation for this, and how to fix it? I've searched this forum for help but failed to find any info. This is the page I should appear on, but don't: https://www.physicsforums.com/memberlist.php?&order=asc&sort=username&page=1033 [Broken] Neither does another name I often use on forums (skylark). When I tried to register here I was told it belonged to someone else. An invisible person, clearly. Thanks..
