If you are not sure please have at least one other person proofread your work before sending it in. We cannot post tips or articles that don't meet a minimum standard of grammatical decency. The paragraph above takes care of most of it, but if you want to improve the chances of your submission being posted keep your writing clear and concise. Tips can cover any topic related to game improvement, from the mental side of the game to basic fundamental drills. If you come from the heart and your topic is important in your opinion you will probably convey that in your writing and your submission has a good chance of being posted.
Articles can cover any topic that is golf related.
That's pretty broad. Again we reserve the right to refuse posting to anybody, but submissions of all types are welcome, from swing mechanics to fiction, all game is fair.
