I think that you gaining the founder position is a bit of a stretch. Technically you can't become a founder unless you started the whole thing yourself under your name. The highest position you could get is co-founder, as you helped build it and improve it. But you do have justification for taking ownership of the Wiki itself. So you can become the owner, but not the founder.
Author Response: I'm not taking "ownership" of this FANDOM Wikia. In fact, that's not something that sits well with the FANDOM Guidelines. Everyone who uses this Wikia contributed to this wiki community in some ways or another and technically, everyone plays a part in the ever-evolving community we are building up currently. In the FANDOM Wikia, a founder do not "own" the community they founded, but can set the early direction and design of the wiki, along with choosing who gets to join the local admin team (as stated in the Community Central). In addition, there's a thing called the adoption policy, where a user can request to "adopt" an (inactive) Wikia with little to no content and/or inactive administrative team if and only if they had met the requirements of what is needed to have the request be accepted by FANDOM.
