Hi Craig. Waray-waray is a language spoken in Eastern Visayas region in areas like Samar (remember the island swept by Typhoon Haiyan, yep, those people were Waray). I don't know if you can find any Waray teacher online but in case you can't, any Visayan dialect (Bisaya/Binisaya) will do. Cebuano perhaps since it's the lingua franca in Visayas and some parts of Mindanao, and is closely related with subtle differences with Waray-waray. I don't speak Bisaya but I know these things because my maternal grandmum was a native Waray-waray speaker while my dad was a Cebuano speaker and they could get along really well - alienating me - a Tagalog speaker. I intend to learn Bisaya someday to find connection with my relatives there but which dialect, I haven't decided yet after all I don't consider it a problem. Good luck! :)

Let me get this straight....Waray-Waray is a dialect of Leyte (northern part, wherein Tacloban City is the capital) and Samar. My dialect is Waray-Waray coming from Tananuan but spent my adult years in Manila. I am fluent in Waray-Waray since it is one of the languages I speak at home (aside from Tagalog, Spanish and English). I don't think anyone teaches Waray-Waray but if you are interested it is not really difficult to learn. Most of the words spoken in Waray-Waray have Spanish origin as compared to Cebuano which is spoken in Southern Leyte and of course Cebu. I don't think there are books either about waray-waray. My cousins spouses are all from Manila and all speak fluent waray-waray having picked-up the words from family conversations. I am sure you will soon learn if you have someone to speak with. Good luck !
