Quick question, i have my 1 node in a very secure location, and is running 24/7.  Is leaving the wallet open all that is needed to make sure the node is online?  Is there anywhere to check to see if the node is online to the rest of the network?

I checked

and it says its valid, i just wanted to double check.

congrats on the 50k, got my 1 node up.
