So I'm having this major issue. Before I had an account on arqade I posted a question Is it possible to make a moving platform below a player's feet?. then like 5 minutes later I decided I should just get an account. later on the question I posted as a guest people started to ask questions with comments and since I just got an account I don't have 50 rep so I can't comment back. so how do I reply to their comments. can you give me answer fast cuz the people are getting ticked off that I'm not replying.
Your "guest" post is actually owned by a separate account than the registered account you're using. You can see the page for that account by clicking on the username that shows below that post. What you want is merging that account with yours.
