I've been a Wikipedian for over a year. I edit Wikipedia as a hobby.
If someone asked me to give advice to a new Wikipedian whose edits keep getting reverted - don't give up! Don't write biased things in articles, and NEVER use unreliable sources. Ask your Wikipedia mentor for advice, and head to the Teahouse to get help. Overall, just don't give up and keep on editing! Your edits will eventually stop getting reverted. It's a learning process! <3
