Yeah, try to make any substantive change on many pages and you'll get met with a barrage of "WP:OR! WP:POV! WP:NPS! WP:WTF!" and don't fall into the amateur trap (that certain editors hope you will) of reverting their reversion. They'll look to get you blocked for a revert war. "What should I do then?" "You should respond to my comments on the Talk page for why I reverted you." "But you haven't made any comments on the Talk page about that." "That's beside the point."

For a few years now Wikipedia has had a mentorship feature where every new user can ask an experienced user for help through the homepage. They usually come through and help you go through the alphabet soup.

Well then, make that comment yourself and you can go ahead and revert it later if the other person does not respond.
