Is there an uninstall tool?

I installed phpbb and don't want it now... Do I simply just delete the folder and drop the DB for it?

If you installed it manually, yes that is how you "uninstall" it.

If you used Softaculous, then you should do it via that tool. cPanel --> Softaculous --> your phpbb install --> should have an "X" icon to remove it.
