Hi, I have a post at
but I cannot makr the replies as "Helpful" or "Correct". Please help.
The user account was originally authored that thread (user account "987213") is not the same as what you used to reply to it (user account "user9358016").
Only the original author can mark replies.
Only the original author can close a thread as "Answered".
If both happen to be YOU, then make a decision as to which one you will abandon and never use again.
Use only one login account and you will not be confused as to who you are, in the future.
