How to rename the wire in elgg-1.8.16 ??????????? HELP

Hello after a few days of searching there is no clear instruction or tutorials or plugins to rename the wire to maybe somthing like posts or other names that admins may want to use, i am willing to change the core files as having the name the wire is not original at all for someone trying to be original, i would really appreciate some information and help and maybe a plugin? i noticed there is a plugin but it does not work for elgg-1.8.16  only for 1.7, should i down grade elgg? : (

Please help me : )

 

this is the only thing i could find that made me so happy until i relized i could not use this plugin
