How do I delete a message I've sent mistakenly

I’m terrbly sorry for sending many stupid messages.
I’d like to know how to delete a message I’ve sent to the forum by mistake.

I also would like to know where I can ask questions abuot English grammar. I’m not a paid member.

Thank you very much.

Sorry prime123 but you can’t delete forum messages at the moment. We will add this feature when we get a chance.

Regarding English grammar questions, as a free member you can ask them in the Open Forum on English where some of our other members may answer them. As you seem to realize, our tutors will only answer questions from Plus and Premium members in the Ask a Tutor forum.

Kindrey’s right. I just accidentally answered a question in this forum, because I was reading just for interest and answered by instinct. As a tutor, I usually only answer the questions in the Ask a Tutor forum.

Thank you Kindrey and Juliroze for your answers. I think I’ll consider becoming a member.

I might misheard her but I heard “an” very clearly.

So I thought it a bit strange, and I wondered what exactly the teacher said.
You cannot put the indefinite article “an” before a possessive noun, though.

Thank you very much.
