This isn't some weird scam to capture your details or sell some database, but likewise don't be a muppet and enter in anything you wouldn't have on a business card either if you don't want to.
Note that we manually verify and approve everyone that applies, so provide as much detail as you can cause we will be checking all your links and references! If if you want to leave the GIG community at a later date you can easily do so via this link.
