I ran a search of GT and also the forum and found no mention of Creeds tune "What If".. You possibly read a link elsewhere on the internet.. All song taught verbatem have to be licensed.. you can however get help learning the style of certain artist, and possible other student liking the same artist could help yuo out..
You can repost to the administator, but i would suggest in the meantime you take a look through the site to see all it has to offer..
Good luck and keep on playing
Gordon..
