I am the Cofounder of Equipify, and I just want to thank everyone for the feedback on this thread so far. What the admin points out is correct, at the moment all agreements are between the two individuals. There are many rental agreement templates online (or check out the template your local surf shop uses), but I would certainly want to check a renters experience beforehand also. We hope that the social media tools on the site will help to do checks on other Equipify members, and we also hope to have some additional trust building tools integrated into the site soon. With our current format it is possible to create a listing as a guide, and you can also sell or lend any type of outdoor equipment.
Thanks again everyone for the feedback. Feel free to shoot me an email if you have any questions - firstname.lastname@example.org I will also check this thread often.
