hello guys and thanks for this great language choices.. i am developing a forum with 1.7.7 version of smf and i just installed the Greek spanish and french languages, well i have the language drop down mod and i can choose the language which i want. the one thing i can't figure out i have installed an invite mod but when i will choose other language then english it will not be visible any more in the menu, only i can see the picture before to it but the word INVITE will gone. and the other thing is it possible that if i will select other language then english so the posts on my board will also convert to the other language?
