I noticed that after you submit a requested tab and change tuning for example, it no longer counts as a requested tab.
But what if the requested tuning is wrong? It happened to me that I changed the wrong tuning of a request and the tab didn't count as a requested one. The tab is here and the request is also still on requested tabs.

Also about the tab type. I do GP tabs and if I want to tab a song that was requested as text tab, I can't do it. Is it okay if I export the GP tab as text and submit it and also submit the GP tab?
