Hoo hoo do I ever! *calming down*
Few things - your age listing says you're youth, and your occupation is student. Every riding association has a delegate position mandated for youth, so you might want to find out when the delegates are being elected, and get that one. Campus clubs are also eligible to charter with the NDYC, and recieve delegate spots to federal convention. So, If you're at UWO, I do beleive there is an active club there - make sure they get chartered! If you're a member of a union that is affiliated with the NDP, they should have spots too (and the good thing about that is that funding often comes with it - the riding association would be second best, likely, for sponsoring you).
Convention can be expensive, with transportation, accomodations, delegate fees, food, and possibly recreation. Save receipts, and remember to apply for travel pool - it can be a lifesaver. ONDY and the NDYC might be able to help with that too. University residences, hostels, billeting (last time the NDYC and ONDY worked together for that) can all really cut down on costs, or getting a room at the hotel or nearby and shacking up with a bunch of people. Or, again, if you go with your riding association, lots of time nice, older delegates who aren't so strapped for cash will share their room with no cost to you. Register early, to get the earlybird rate, and complain like hell if, when the fee schedule comes out, there isn't a low youth rate - send emails to the NDYC, federal President, Jack, federal secretary and the treasurer, at least.
Conventions can be tonnes of fun. Read over the plenary rules, so that if you want to speak on something, you don't annoy the chair too much. Don't feel the need to stay on the floor all the time, since the chatting can be the most fun and educational, but caucusing in the bar only isn't healthy either. Avoid the meetings of the socialist caucus - there are great people in it you can talk to at the socials afterwards, without having the hang with the crazies. Come to the NDYC. Bring money to buy cool tshirts, books and buttons.
And don't get too down on the party - I've wanted to quit after each convention. Its the best and worst of the NDP, packed into one sleepless weekend.
Hope to see you there!
