If you were to fix the language errors with Archbish's help, you could then submit your story to the archive in a very short time - this is good. Very good. We like to see stories make the archives.
Don't wait and fix it later, especially if you're also writing other stories. This story should be on the archive!
Yes, you're right. Actually, I had a few problems with my mail box for some time (I can receive mails but not send it), so I didn't responded immediately to Archbish. But I finally used another mail adress to send to him a mail to ask his help to me edit my fanfic. I hope he'll accept. If so, my story will be ready to go to the archive sooner.
Thanks for all the feedbacks. I really appreciate it.
