Well done on the place, I'm still waiting to hear about mine! I will (hopefully) be using justgiving for fundraising, because...
1. The more channels you've got for people giving you money, the better. There will be lots of people I approach who haven't got access to internet, but probably a lot more who do.
2. People pay up front. If people are asked to make a donation online, there's just one visit involved to get money out of them. From what I've heard, this is one of the main benefits as it saves the hassle of physically asking for people for money they've already pledged after the event, i.e. when you thought all the hard work had already been done!
3. I've also heard the argument that faced with typing numbers onto a page and giving credit card details, people tend to part with more cash. Typing 2 & 0 on a screen somehow seems a lot less financially painful than passing over a nice crisp purple note!
4. And a hint that applies to other sponsorship forms as well - get the person at the top (your beloved yet wealthy relative, company's MD, etc) to sponsor you a big fat wodge and this will set a precedent for other people deciding how much to give you.
5. Convenience. Once you've got the page set up, all you have to do is send out the URL whenever you can - leave it as a link to all e-mails you send out, signatures on forums, etc etc.
Good luck!
