Websites and Blogs
Talk about your nights and promote them. Start a blog. You can use it to post photos, playlists and general news. There are plenty of free blogging services.
Events
Publicly announce your noWax night? If you're a member of a social network like MySpace or Facebook, create an event announcement there. Become a noWax friend on MySpace or join the noWax Group in Facebook.
Photos
Upload your photos onto flickr or any photo site that you use and tag them 'noWax'. Join the noWax international group on flickr and you can add your photos to the group pool for everyone else to see.
Press
Contribute to a cupboard of press and web articles that tell the story of noWax. Create a del.icio.us account and tag your news link with 'noWax' and 'press'
