Would be nice if one could sell shares don't you think?
That's not the point of the exercise, although I wouldn't mind a re-weighting option so that it's more reflective of real portfolio management. There are quite a few dummy account options around as it is.
The only issue is that it will be a little too true to life, in that you invest and forget about it. Most amateurs will check every hour or so at first, then every day, then every second day, until they eventually lose interest as there is no possible manipulation of the portfolio in any sense.
I'd say allow some re-weightings and add another asset class, preferably a derivative, and preferably index futures.
^^totally not biased - that was just a random suggestion^^
