Your submission was rolled back because the only content you added to article was the website address "opencaching.us". It is in their policy to roll back that type of edit. It smells a little like spam when someone only adds web addresses. The gc.com stuff was probably in there from the article creation back in 2006.

External Links that Should Be Deleted
*Links added by someone who has not also significantly edited the article. Editors who only place external links without making other significant improvements to the article should be rolled back without even bothering to check the link.
