Welcome!
Hello, and welcome to Wikipedia! Thank you for your contributions&#32;so far. I hope you like the place and decide to stay.

Here are some links to pages you may find useful:
 * Contributing to Wikipedia
 * Tutorial
 * How to edit a page and How to develop articles
 * Simplified Manual of Style

You don't have to log in to read or edit articles on Wikipedia, but if you wish to acquire additional privileges, you can simply  [ create a named account] . It's free, requires no personal information, and lets you:
 * Create new pages and rename pages
 * Edit semi-protected pages
 * Upload images
 * Have your own watchlist, which shows when articles you are interested in have changed

Note that in order for the first three features to be available, you must have had an account for a minimum number of days and made a minimum number of edits.

If you edit without using a named account, your IP address (2409:4050:E9B:42C2:505E:9DF1:4B53:56A6) is used to identify you instead.

I hope that you, as a Wikipedian, decide to continue contributing to our project: an encyclopedia of human knowledge that anyone can edit. If you need help, check out Questions, or you can  to ask for help on your talk page, and a volunteer should respond shortly. We also have an intuitive guide on editing if you're interested. By the way, please make sure to sign and date your talk page comments with four tildes (&#126;&#126;&#126;&#126;).

Happy editing! -BigDwikitalk 18:10, 1 November 2019 (UTC)
