Some Hints for making a successful Charity:
1. Have it planned out before your first post. What will you donate to each person? How will you pick the people to donate to? Will you use special rules to make sure they read the rules? How will you acquire the stuff to donate? Larger donations are cool but harder to finance. If you don't think you can pretty much fund the charity with just you and the staff you have on board, you may wish to rethink the idea. Few people actually donate significant amounts to charities regularly.
2. Plan your thread in an offline word processor post by post. You may want to reserve all 15 posts of the first page so no one can stretch the page or otherwise mar your presentation. You'll probably want the following posts: Introduction, Rules, List of People who donated to your charity, List of people that the charity has helped, Staff members/story of the charity, Contests if any, Affiliates links including banners and links to your charity for others to use to advertise your thread. The order of posts isn't really important. Many charities include a Table of Contents on the first post.
3. Collect a good-sized "pot" to start with before opening your charity (at least 10k, preferably more like 30k-40k).
4. Beautify your charity with artwork that goes with your charity's theme, but try to keep images small so they load faster, especially for our dail-up friends.
5. You might wish to hold a Bumping contest to get your thread rolling. If you hold a lotto you might want to check out
this thread of rules about that.
