If you are new to wikis, you should go to the tutorial on the Central Wikia.
To introduce yourself to Fantendo's community, go to the the Community Portal. The Community Portal is also where discussion, enquiries, and proposals can be made to Fantendo at large. You can do the same to a single article on each article's talk page.
It helps if you sign and date your contributions by putting four tildes (~~~~, it's right by the 1 on most keyboards), so that readers know who to talk to and whether your message is probably still of current interest.
Do keep an eye on the recent changes, where all edits (good and bad) and their authors (anonymous or signed-in) are listed.
Remember to categorize your articles. This is one of the most important part of making articles.
Please stop spamming delete templates and reverting sysop edits. This isn't a warning, and it's possible that you made a mistake by accident or without realizing it; this is simply a reminder for your information. If the action continues deliberately, then a warning will be issued. Thanks for reading and keep contributing.
