Just a quick note to let you all know, you can now logon to all servers using Minecraft v1.13.2!!
Just keep in mind, as it tries to "convert" things from one version to another, it may not be optimal. For this reason, if you're going to really play on one server more than any other, I suggest you play on it's native version 1.12.2 (ahem... Towny).
We are in the process of converting many of the servers to 1.13.2... please stay tuned ;)
