Text amendment on field in Fundraising plugin

Dear Staff,

I purchased your Fundraising plugin today and I have just noticed there is a missing "s" in "Address" in the second field before processing the pledge, therefore I was wondering how to amend it.
Further, I expected to have the opportunity to add useful fields and option (for instance the mobile number when I may notify by sms when the budged will be reached or where collect additional information).
Looking forward to receiving your reply.
Kind Regards,
