Only if that is what you want to do. What I mean is to have the wiki move to The jkcoin.com site and having the the current address point to the wiki on jkcoin.com. It would your choice if you wish to maintain the wiki on jkcoin.com or let somebody else.

Or do neither and keep your wiki where it is  

I am just trying to consolidate the web resources to one place, and it would save you hosting costs.
