The series Machicado Mazoku has two communities dedicated to it, Wiki A and Wiki B .
Wiki A is much better managed, however Wiki B shows has better SEO and shows up first in searches. I find having two communities not only confusing, but also hindering the growth of the better managed Wiki A. I've tried contacting the Founder of Wiki B regarding this situation but they have been inactive since August 2019.
Personally, I'd prefer Wiki B to be deleted, or turned into a redirect to Wiki A, if ever. I'd love to know your response, thanks!
If wiki B is active, then you need to have a discussion with the rest of the wiki B community to agree that you should be admin. At that point, it might just be quicker to discuss merging directly rather than discussing your candidacy for adminship and then discussing merging.
The admin need not be active, although if only recently so, the courtesy of reaching out to them is advisable. But any active community users of any level should be asked their opinion (use actual discussion threads, no polls, which can too easily be gamed)
Understand that there is nothing against there being more than one—or more!—wikis on FANDOM about the same topic. This is not Highlander, there need not be only one.
That said, Mergers *do* happen when all involved with both communities think it a good idea and beneficial.
