Use good grammar and use grammar well. End of story. Unlike essays, which are incredibly subjective, grammar is objective. Unfortunately, most forum members of any forum suck at using proper grammar. Whoever uses bad grammar, including moderators or administrators, is a total n00b.
Also, TITLE YOUR THREADS APPROPRIATELY! Don't make a thread saying, "i need help!!!!PLZ rspond!!!"
1. There are too many exclamation marks.
2. The title does not summarize the thread neatly, but rather makes the reader confused.
3. Capitalize "i" and write out "Please."
4. Don't skip any letters. It's "respond," not "rspond."
