Knowing that the sponsors are helping you to fund the costs involved with the forum I would have no issue with whatever exposure you allow them Frank. As a relatively small community compared to .com for instance I am really appreciative of the support they extend.
Domain Name Forum: We list sponsors offering Domain Name Registrations
Domain Services: We list Sponsors offering Web Hosting
TBR Domains: We list Sponsors offering TBR Services
All sponsors get the Main Page Index listing but the individual forum listings are only available to sponsors offering the service.
So since FullHost does not offer TBR services they are not in the TBR banner but they are in the Registrar and Web Host banner.
This way when someone visits the TBR section they know every sponsor listed in the TBR banner actually offers that service.
We encourage members to support the sponsors that have contributed to our site expenses. Without them we would not be able to maintain our cloud servers thus offering free services to all our members. Please show them support by visiting their websites and using their services.
