Pwake - Wake up call pairing

I collect contact info from individuals who want a wake up call at the same time and pair them by geographic region so they can phone each other.

This service not automated, complicated or scalable. It uses a Google form to collect information, which is appended to a Google spreadsheet that I have access to. It is hosted on neocities.org, in case I wish to add informational pages in addition to the sign-up form. I manually verify, pair and contact participants.

My goals are modest, 100-300 users, so that the chances of finding people who match are good. If there were more than 300 users I would not be able to administer it manually.

Are there any changes I could make to speed adoption or increase usefulness?
