Welcome. Some good tips...
Don't spam, meaning don't post the same thing more than maybe twice
Don't type in all caps or big fonts to make your point, let your words do it on their own, same goes with using lots of colors
Avoid the 'wall of text' which is writing a long post and not using paragraphs or breaking up the content
If you post a video, give a good explanation of it
Try to avoid getting too long and wordy, the longer a post the less it gets read
Make sure to post in the appropriate section
Those are some good ways to get along on here better.
