I use Flash FXP to create my webpages. It costs $25, but it is very worth it - it is so easy.
No matter what you use to create your files, I would suggest copying the code onto a school-hosted page. Your college probably would give your organization a free website like
www.collegename.edu/clubs/sororityname . It would be easier for PNMs to find the site, and it would be ad-free.
You might be able to create it with a free program (I have even used livejournal.com), view the source in internet explorer, and copy and paste it to notepad to upload to your school site.
However, I can definitely recommend FXP - it's a little pricey, and you have to use HTML, but it's worth it. The HTML is not that difficult, and there are many online resources. If you want help getting started, feel free to PM me.
