Apologies in advance for posting this here, but I don't know where else I can ask for help.

1. How does one delete a message on Flyertalk? I've tried following the instructions but they just don't work.

2. Today, I am trying to post a reply to a thread and Flyertalk is saying that my message is a duplicate of a message I posted 5 minutes ago but I haven't even logged into Flyertalk for almost 2 full weeks, much less posted anything 5 minutes ago or even 5 days ago. Any idea what this means and how to solve?
