Why have I been denied the right of presenting an answer to the posed questions.??..my direct email has been ignored?

Is it just on one Particular Question ? if so the Asker may have Blocked you

Another Reason could be

You may have Reached your Daily Limit for the Day if thats the Situation you have to Wait til Everything Resets again for the next day at 8:00 pm PST Pacific Standard Time

You are blocked from answering any question this person asks. If you emailed Yahoo it doesn't help because the user has the right to block anyone he or she likes. Just need to accept it and move on.

There is a daily limit to the number of questions you can answer. You may be blocked by the user whose question you tried to answer.

You didn't say who you emailed, so we can't say why that didn't bear fruit. There is no Yahoo contact for inability to post, and not all users who allow email contact will reply (some don't even check the email for the account they use for Answers.

You will not be able to post if you have reached your daily limit or you try to put a percentage sign in your posts, and you will not be able to answer questions if an asker has you blocked or the question is closed.
