Getting desparate, that's the best you have. "Center" versus "Centre" depends on the context. In Canada, the two words have different meanings.
centre is a place where people congregate, e.g. shopping centre, town centre (building).
center is the central point of something, e.g. center of a graph, center of a map, etc...
