Can't I comment in threads I made in game buy/sell forums?

Or I'm just blind. I honestly have 0 idea how to comment on my own thread, lol. Wanted to say I got something new in my account.

Seller's cannot reply directly to the own thread. If another member makes a comment, you can reply to that comment.

You can edit the thread to fix something. Sorry.
