in is also a loop and it seems (use markdown formatting when posting code here, so it keeps indentation and can be read) nested to your for loop, that won't work.

to add to this, those who type the same clan name will be added to yours. so type a clan name(case sensitive), and send it to friends / peers, asking them to type the same.

You just type it in your account settings. There aren't really "clan" functionnalities, actually.
