Forum:Two wikis about the same subject - which one should I edit?

I'm interested in editing a wiki about Fetch! with Ruff Ruffman, but there are two wikis about it - fetch.wikia.com and fetchwithruffruffman.wikia.com. Both are run down and have about the same number of pages. I'm not sure which one I should edit (it would be a waste of time to edit both wikis about the same subject).

Request for a merge, or import the best articles onto one wiki and request that the other be closed. Easy. --Thenewguy34( Other) 23:06, May 28, 2012 (UTC)
 * Pick one that makes more of your interest. It's best to pick one with a more stable community, better spam/vandalism patrol, and more information.  :)  -- 23:21, May 28, 2012 (UTC)
 * How do you request a merge? Do you use Special:Contact? PSH aka Kimera 757 (talk) contribs) 00:16, May 29, 2012 (UTC)
