I have found the following things help when using the threads to find information:
1. The first page usually has a summary of what is known of requirements needed for various stages of the event.
2. The last two pages usually have requirements for later stages of an event that may not have been posted to page one yet.
3. If you are able to follow the threads, log on early. Visit daily-usually there won't be more than 1 page of new posts so you should be able to follow what people discover as they complete requirements.
Any other tips out there that people have found?
