Yes, server plugins. Oh... I thought mods is meant for Minecraft Mods not for server plugins.
But I have another question is there http://www.planetminecraft.com/resources/projects/ projects in here, which have plugins included to fully functional? For example: if there would be tnt run project, there should be tnt run plugin inside that project. Tnt plugin function would be - while you walk on tnt it dissapears.
Would be accepted, but the only problem is, as I checked You haven't ever been connected to the server, that's strange, are you sure you provided the right nickname?
