Hi, welcome to Wikipedia. Regarding your question about Filter 139, the page Wikipedia:Main Page/sandbox isn't really supposed to be a place for editing tests, for that you should try out Wikipedia:Sandbox. I did however modify the filter so it will no longer prevent the edits you were trying to make. You may want to consider registering an account, which requires no information, not even an email address, to avoid potential problems like this. Let me know if you have any more questions!

This is the discussion page for an IP user, identified by the user's IP address. Many IP addresses change periodically, and are often shared by several users. If you are an IP user, you may create an account or log in to avoid future confusion with other IP users. Registering also hides your IP address.
