The new ArkGeo banners for cache pages are GREAT!! This is exactly what I've been looking for. I would encourage ALL Arkansas geocachers to use these banners on all of their cache pages, so that everyone who visits your cache will see them!
Initially, I had put links for both the web page and the Yahoo! group on my pages, but now I've removed the Yahoo! links for several reasons: 1) The web page seems to me to be the best long-term solution. 2) It removes a level of confusion for potential members by having a single POC. 3) The web page has links to the Yahoo! group, if needed.
