If you already have a W-9, it's fine to use that one or here's link just in case: http://www.irs.gov/pub/irs-pdf/fw9.pdf. There are two ways to submit a W-9:
1) Email firstname.lastname@example.org) Use file.io to upload and send the link to Melissa at email@example.com. Please note: if you use file.io, do not check your link to make certain it works! One of the security measures of file.io is that the link only works once. After that it disappears! (If you open it, we can't!)
Please let us know if you have any questions via firstname.lastname@example.org.
