I like it how it is and can think of a few good reasons why itís built that way. Going back to the topic youíve posted to gives you a chance to check that your post was actually posted; that what you posted was understandable and made sense, and that it wasnít riddled with spelling and grammatical errors.
Giving an either or option, which is presumably what youíre suggesting, would either entail the insertion of another page displaying the options or some major juggling with the cookies to select and keep your preference. Unless of course you set it in the user profile, but whichever way you look at it it would, in the long run, require more work for the server.
Of course this is only my uneducated guess, Iím sure Ron can elucidate far better than I can on the technical implications.
