Yep we are, but at the moment you're in charge since I'm currently on break... again. :P Sorry, in June I went to camp and when I came back I couldn't get back into BTFF (I mean I just didn't have the same enthusiasm for it) but I will return. And I'm still active on Wikia in general so I'll respond to a message whenever you need me. ;)
Can we also add a rule that we can not accept series that are barely editted and contain unoriginal content (ex: Pokemon10). It's sort of confusing when editting and since its a Ben 10 Fan Fiction game, I don't think mixed fictions are such a good idea.
I don't know, I think barely the editted ones can be included, since the series could be new and as long as they have at least a few completed episodes (3, 4, 5, etc.) it's fine. But just not the unoriginal ones; With "unoriginal" being stuff like "random-other-show's-main-character-gets-Omnitrix", as the use of "unoriginal" could also decribe the commonly used story format of "Ben-gets-the-brand-new-super-cool-Omnitrix-and-fights-aliens-with-it". The former example would be "unoriginal", while the later is acceptable.
There's not much needed to know. If you mean make a series page, it's just like any normal page: click the arrow on the "Contribute" button found in the top-right corner of the screen and a drop-down menu should appear. Select "Add a Page", wait for the pop-up and enter your page title in the field and select the layout option, I prefer to use the "Blank page" option. Besides that, there is a link to our wiki-exclusive Page Creation Portal (not neccessarly on this wiki only, but featured on some others too) and scroll or select in the table of contents the "Series page" selection and create the page. ;)
