Installation ESP8266 ERROR

Hi every body,
Before using the present way to try to get an answer, I have searched around for a long moment on this site the way to write a new post : unfortunately, I have been unsuccessful.
So, I use it, and, Segundo, please receive my apologizes to interrupt your question.

My question is the following :

HOW CAN I WRITE A NEW POST ON THIS FORUM ?

I have an important (for me) question to ask, and I am sure a lot of people using this forum will be in position to provide me with a very simple (for them) answer.

(to the moderator : I understand you perhaps will delete the present message. If so, could you anyway be kind enough to provide me with the answer to my question? - This is the only way I have found to get my answer.)
