Just wanted to mention the much-cursed backspace problem on here, if you're using Firefox there's a simple solution to the problem. If you're using IE, it seems to be harder - involves adding a script to the webpage itself, which, naturally, you can't do yourself but Ryan has to do. (Trap backspace in onkeydown...)

(And for those who don't even know what the backspace problem is; xsketch is built on a webpage, and IE and Firefox are designed so that if you press backspace when you're on a webpage, it is interpreted as if you press the Back-button [back to previous webpage]. This turns out to be a major cause of frustration on xsketch when you chat/guess and somebody sits in or out, and the textfield (that you type into) therefore loses its focus. So now that you don't have focus on the textfield, and press backspace, the web-browser reacts with a "ok, you wanna go to the previous webpage", which normally is the previous table you were at. Ie. you're thrown back to 0-table, and have to change back manually to the table you wanted to be in ;-) Long explanation for simple frustrating matter. Use Firefox and fix it as described above.)
