If you read the COTM for January 2018 nomination thread, you might have seen the change for nominations.
You can now nominate either a cache or a series of caches! If you nominate a series of caches, just include the GC code for the starting or final cache of the series so others can reference the caches you are nominating. We know there are some great series out there, so let's start recognizing them!
If you have any questions regarding this change, please post below or email the email@example.com.
