In order to complete the Wherigo on wherigo.com, a code which is generated at the end of the Wherigo must be entered. The problem is, that there's a disconnect between logging the Wherigo on geocaching.com and logging it on wherigo.com. Logging it or failing to log it on wherigo.com has no bearing on the ability to log it as "Found" on geocaching.com, and when it comes down to earning that golden smiley, its the log on geocaching that counts, not the one on wherigo. I've never seen that logging a Wherigo on the Wherigo site affects anything. The only requirement in the guidelines to log a cache find is to sign the log and there is no distinction made for a Wherigo cache, possibly because the physical cache typically is found as the final step in completing the Wherigo.
