Hi Nina,
When you said you "Used Cathal's suggestion" - did you mean this one? http://www.dnnsoftware.com/community-...
I wanted to try that. I found that the referenced resource (PublicMembership.Text node in App_GlobalResources\SharedResources.resx) DIDN'T have the same text as the site displayed, and changing the resource didn't affect what the site displayed. Is that the exact place you changed?
Trivia - you might want to review your sig. For "If it's on DNN, we fix, build, deploy, support,skin, host, design, consult, implement, integrate and done so for over a decade." Read "If it's on DNN, we fix, build, deploy, support,skin, host, design, consult, implement, integrate and have done so for over a decade"
