Get Satisfaction.
I do not know if any of you have noticed the tab on the left hand side of the screen on Geocaching.com. The one that is labeled "feedback". This is a special link to the website Get Satisfaction.
This is a way for the geocaching community to post bugs, praise, and ideas for the lackeys at groundspeak to see. If you have not been there it is a great way to see if some ideas are planned, not planned, or under consideration by geocaching.com.
Here are a list of a few of the most popular of them.
Bring Back Virtual Caches Under consideration
Create a "Nano" Cache Size Option Under consideration

There are hundreds of others. So take the the time to toss a vote in.
