Hey guys, I've taken the plunge and have started to write my first fan fic. I have a beta reader and she is teaching me between the past and present tense. I write then send to her what I have written and Im still confused about this past and present usage of words such as have, had was, is etc. I read it out aloud and it sounds alright to me and I still get it wrong. Is there a thread on here explaining how to get it right? Would appreciate any help. Thank you in advance.
