I'm currently unaware if I can even get prizes, since the WiFi I use isn't our own and sometimes disappears. I'm still around though, not to fussed about the prizes as they're just an added bonus. Perhaps when the club was to get renovated we could have something like a rating system, so you could earn points freely but depending on how loyal you are to the club or something like that, the prizes you could trade your point in for would improve. So newbies would get the bare minimum but if you work hard and become a real part of the club with the support that they show they'd earn better trade ins.
As an extra note, with the Pokewalker that's part of Heart Gold/Soul Silver we could add some of the rarer obtainable pokemon on there as possible prizes or possibly some rare candies (as I'm working on my ruby for a Linoone/Zigzagoon team that will gather me candies and stones on Pearl, but they're also amazing for gathering me candies on ruby). I think anything we offer will depend on how the club gets designed when we start again, but I also think we shouldn't be limited to cloning talk as we often run out of things to say. Just a thought, but couldn't we open it up to talk about all glitches and stuff and how related things within the 'real world' compare to them just to open the chat possibilities up a little and there could be occasional, regularly scheduled competitions such as designing themed banners around certain holidays and similar stuff, just to get people involved.
Just my thoughts, I could possibly add more but I have to get ready for work or I'll be late so I may add more later. Anyway, it'd be good to hear everyone elses opinions on this stuff as well, so feel free to be vocal about it.
