Not everyone who helps out with answers on this community is an AGL employee - some are just customers like you, helping out and sharing their knowledge in their spare time. If someone has taken the time to help you out, saying thanks is as simple as marking their response as the solution, clicking the Like button on their post, or just dropping by again to reply to them.
A little respect goes a long way!
