it takes a while for your nodes presence to be detected on the network. Basically, nodes that connect to you (node A) say "oh hai, now I now you exist, I'm going to write down your number". And then when that node connects to another node (node B), the node B says "hey, how many nodes do you know?" and node A goes "here's my list. They're cool people". And node B goes "ok thanks bye." And then node C connects to node B and goes "yo I needs some nodes to connect to" and node B goes "Oh I gots a list".

So who knows where monerohash.com is on this list of sharing in relation to your node.

It will take a while, but you're on there. Make sure your ports are open too. Check your firewalls and open 18080
