I experience the same log-in problems described here. Geocaching.com won't remember my log-in, neither do the Groundspeak forums. Additionally I found that also the API permissions don't seem to be remembered. At least I can't load PQs via Locus (a GC live enabled map and navigation application for Android) without acknowledging the API permissions every single time. And even then it claims there wouldn't me any PQs ready although they clearly are. Of course this could also be a problem with the 3rd-party application but it fits in quite well with the recent log-in problems here, I think.

To answer the original question: No, I won't do challenges. In my opinion, geocaching is about searching, finding and signing a logbook in a container. Nothing less. I don't even do earthcaches because I don't consider them being real geocaches. Only thing I could imagine as a worthwhile challenge would be e.g. "Find soandso many caches in thisandthat area" or "Find all caches of a series" or something like that. But not tasks like "Take a photo of a specific landmark". That hasn't much to do with caching anymore.
