I am having trouble getting approved links to work. I tried with both google meet and zoom and both of them seem to return Invalid Link. I could be the one doing it wrong but I am not sure how else to try.

@nora-zajzon, for Google Meet: Did you have a link like https://meet.google.com/bgc-szbm-osr? I was able to add it. Can you retry?
For the Zoom meeting: At the moment, the Zoom regex won't match Zoom meeting URLs with a subdomain like ucsd. Will HackforLA use Zoom meetings with subdomains? I can add that.
Hope this helps, and thank you for reviewing my PR.

Hi @JackHaeg and @trillium, do we allow users to enter relative URLs (those that omit https://)? Also, do we permit users to use Zoom meeting URLs with subdomains? I will move forward based on your feedback.

Do we allow users to enter relative URLs (those that omit https://)?

Yes, please allow for the https:// to be ommitted, as well as www.

Also, do we permit users to use Zoom meeting URLs with subdomains?

Also yes

Thanks for asking for clarification!
