The worst advice is that, concerning roleplaying is that people look for excellent grammar like it's gold. When I was coming up we were high school kids fresh out of second period English class and we were an imaginative bunch. We had to focus our internet fuzzed minds on expertly using grammar to tell our roleplaying stories. Now, here in 2020 I know that grammar is a basic thing. It's two apples growing on a tree, and one falls down and then the tree picks it up, then the other one falls down and the tree has to pick the second one up. Basically, no matter how many times the apple falls, the tree will pick it up. Your grammar expertise will do the same. You're close to the big tree no matter what about the apple. Grammar Nazis suck! (And I might too because of this thread)
