Well, I have EssentialsX but i see that i need to have basically "EssentialsXChat" and "EssentialsXSpawn". But i don't have them. And i see that when i don't have EssentialsXChat I cannot make
prefixes with PermissionsEx, i tried to see for a solution. And i found that i need ChatEx. I installed it, but when i installed it the ChatEx is in green but the PermissionEx plugin is not there is like im not installed it, when i actually installed it. So my question is. "Basically, Can i use EasySetSpawn plugin for the EssentialsXSpawn (I Already use it btw, but i need answer)" and "Is it needed to make prefixes another plugin for Chat? Like ChatEx or EssentialsXChat" these are my questions 
(Btw, i think this may be a long conversation)
