I completely understand that even $30 is not doable for all, and there is no pressure. My view is that users should be the last to pay for the service. I would much rather have advertisers support the site where possible. Gear retailers, kit shops, etc. typically get very good value advertising here. I encourage folks to talk to those organizations that they deal with and let them know about the advertising options here. Helps support the site without coming out of your pocket and gives the advertising access to a focused audience.
