i have fire fox in arabic so when i visit your site it will redirect me to arabic lang >>this is ok
but i also using ie in english version and it will use your site in english version
is there away to add abilit to make additional factor to this by using geololcation or ip2location that will also increase the best default lang choice for vistor that first time visit main site

another thing :
i requist to highlite the image of the used language in translated page

also which is important for me :
when user choose the default original language of the site
he should get by the default when use the the site without any translation and he want to reply or add thread: the language option is by default for him : Do not add language BBCodes
