REGISTER NOW. Apart from saving the organisers several ulcers by booking early, you'll be doing yourself two favours. Pre-registration saves you a fiver on the cost of registering when you get there, not to mention saving you all that frustration of standing in queues behind people asking for change for a thirty pound note. It also means the organisers know whether they have any extra money for to spend on even more top-class entertainment, workshops and facilities - including possibly the finest juggler in Europe (no, not Haggis, he's already coming for nowt).
Pre-registration forms are available in the Feb/March issue of The Catch, or you can use a copy of the JIS on-line version - (don't forget to send them a SAE if you want confirmation).
