1 - Did you want to apply to several clans and see which one will take you?
2 - Did you want to be in 2 different clans at the same time?
You can apply to as many as you want but only be in one at a time.
It should be possible to apply to multiple clans though you can only be in one at a time. You should be able to go to each of their application pages and apply. There shouldn't be anything else too it. The first one that accepts you will be the clan you end up in and other applications should be immediately removed by the system.
I've applied for one clan,but cannot apply for anymore (it wont let me) the clan i applied for hasn't accepted me. so I'm stuck in limbo (thats not a clan)
That is odd and is not typical behavior of the existing Elite site so not sure why it would be that way now. Not sure what you can do aside from try and contact the other clan and tell them to delete your clan application so that you can apply to another one.
Question just to make sure we cover our ground: Are you sure the 2nd clan you want to apply for is open to receiving applications? Also, do they have room in the clan?
