Some Online Application questions

<p>1) Some of my positions in extracurriluar actitivites do not fit in the box, should i attach a resume? But I dont think they would like reading over the same thing twice
2) Shouldn't there be a supplement signature form that i have to mail in? I cant find it anywhere if there is.
3) What's this undergrad statistical form? It's in the paper apps but not on the online apps
4) I do some photography on my spare time, can I send them some samples? They didn't give me an option on the online apps though.
5) The proove of financial capability is only submitted after I am accepted? (If i am)</p>
