I would have thought a good and open debate about the merits of other software versus Xara could actually help others making the break into Xara or Xara users learn more about this product.
Xara is robust enough to stand on its own feet and not be threatened by comparisons with other brands.
Rather than close a topic as it might not show Xara in best light, or suggest the other is better (which I don't believe it would) or suggest such a topic is not Xara related, I would offer it be thrown open for debate. If its about Xara then it definitely should be here in my view.
my two bobs worth.
