Hey there, I have sorted out some erroneus categories. Mach 5 or Racer X are no episode articles, so they don't belong to any episode category, unless you make articles about episodes with such titles. When doing this you also are advised to follow the specific layout for episode articles. As you are new to this wiki and others have made this mistake as well along with the fact that this wiki is not that well-organized due to its inactivity, I'm not going to block you for now. I'm rather the type of bureaucrat who assumes good faith and is very welcoming to new users. However, please add categories which make sense. Layouts for articles you find here.
This wiki was founded by a former staff member of FANDOM known as Scarecroe. He already turned inactive in 2008, the year the wiki was founded. According to research I made about this wiki 2008 was definitely its prime, mostly thanks to the fact that the live-action movie about Speed Racer entered the cinemas and also an american-produced series started airing. In 2015 a former colleague of mine adopted this wiki. Soon after that he retired from his duties and gave his powers to me. Since then I have started several reforms on this wiki, also due to the fact that a reboot of Speed Racer was announced in 2015. However as the reboot didn't start yet, activity on this wiki continues to be very low.
The reboot was announced back in 2015. However nothing has been announced since then. Due to this wiki's inactivity it is still not that organized. Of course you are welcome to add a category for male and/or female characters.
A reboot is any new work. The reboot of Speed Racer was expected to be a new television series. I've checked your page on that wiki. Categories shouldn't be redundant. If there are for instance characters who appear in Speed Racer X, it is best to categorize them as Speed Racer X characters, as well as episodes of that season should be categorized as Speed Racer X episodes. However Speed Racer X shouldn't be used as category for everything in this season. Categories like Males, Females, Heroes, Villains, Main characters or Supporting characters also can be used.
Speed Racer X was an unsuccessful reboot of Speed Racer which was first broadcasted in 1997 on the occasion of the thirtieth anniversary of the original series. It was cancelled after thirty-four episodes.
Yeah, Speed Racer X was heavily disliked by many fans, something which often happens to sequels and reboots. If you want to include pictures, it should look like this in source mode [[File:Example.jpg]] If you want to have a gallery it should look like this <gallery>Example.jpg</gallery>
You don't have to click on it, you just have to insert the files the way explained above. If you still don't know how to add files to an article I could send you a tutorial how to do it. This page could also be helpful for you.
Positions are mostly given to users in more active times of a wiki and also preferably to very experienced users who at best have knowledge about every aspect of a community. Users in powers preferably should also be chosen by the community.
