Welcome to the Young Set Theory Network.
So here's what you need to know... The YSTN is a wiki, which means that any registered user (with designated 'Set-theorist' status) can change almost every aspect of the site. Registered users can also upload files, which will then be available for viewing by any visitor.
Initially, the site is intended as a repository for short articles on set theory and related subjects. This could include the following: short papers that are not suitable for journal publication, lecture notes, thesis chapters, simplified explanations of existing papers or techniques, book reviews, coherent philosophical essays, and so on...
But the main thing to remember is this: it's a wiki! We hope that the nature of this site, and the uses to which it is put, will evolve with input from all corners of the set theory community. So all ideas are encouraged, and users are free to upload files that do not fit into any of the above categories, or to change pages if they can think of ways to improve them. Here are some notes that will tell you (in no more than three minutes) how to go about using the site:
- How to register
- How to create a new page
- How to edit a page
- How to upload files
Once you've got to grips with how it works, start editing! You do not need to ask permission: in fact, there is nobody you could ask anyway. Once you have registered, why not start by editing this introduction...
