This involves editing the messageboard, which is not totally understood. Get this wrong and the messageboard (and consequently the system menu) will not load and you have a [[brick]]. Now we have some form of [[Bootmii|brick protection]], someone might want to have a go at this but I have no interest in doing so. Incidentally, deleting messages will not free up any blocks for installing channels; the messageboard is fixed at 20MB.
===How about a pie chart?===
I did think about this but was too lazy. Maybe later.
