Here's my attempt at a Dom3 server monitor tool.
It's Windows only, requires .NET, and as all software that doesn't go through Q&A, may crash your PC
That said, I've been using it myself for a while.
Simply enter your server and port and hit "Get Status". The dropdown list should populate when you disconnect, and on all subsequent uses of the tool.
Next version will include the ability to delete servers from the list, and I'm hoping to get the nation flags in there as well.
Without further ado ...
the Dom3 Server Monitor tool.
Please email me any suggestions or bug reports, as I'm not sure how often I will check back here - this tool is mainly written for me, and I'd thought I'd share.
