Please try to work on your Grammar when making edits because some of it doesn't meet the requirements of most English Sentences. Translators aren't the best method to learn English since they're no usually always accurate.
That's why I think people should only edit wikis in languages that they can speak within an acceptable range. Bentenny10's first language is Spanish. I'm guessing that his Spanish is much better than his English. Therefore he should only edit the Spanish wiki.
This is not a case of "the more the merrier" or "the other users will fix it". As Sandra.olhsen said, Bentenny10's English is (sometimes) utterly incomprehensible. This does not apply to Bentenny10 exclusively. A lot of users shouldn't be editing this wiki because their edits are incomprehensible garbage.
How would I go about to make a Swedish version of this wiki? Some other sites like Dragon Ball wiki got a button you can press to change the language. I figured I could start with the original Ben 10 show and then carry on onto the aliens.
Why did you create a category named "Ben Tennyson"? As for your "Protector of Earth Timeline" category, it's not needed at the moment. When the current "Alternate Timeline Characters" category is too cluttered, then you can add it.
