This works for almost everyone.
You have to be a verified provider to post ads. For that:
Submit your info to the staff at
pennsylvania@eccie.net
1. website address (your website or advertising site)
2. referral from another provider or hobbyist
3. links to reviews from recognized members (any site)
Any combination of the above requirements which will sufficiently establish you as a legit provider will be accepted.
The verification process could take 24-48 hours.
