Your posts are delayed because there are so few. WGT moderates your first posts to filter out spam bots, ad bots, and idiots... Usually it's 5 - 10 posts. When they see that you're not any of the above they will 'un-quarantine' your messages.
Now, as for the Swing lessons... everytime I clear my caches I get the same messages. You simply have to go into the settings and turn them off as listed above by Boffmen.
If you have turned them off... and they are still popping up... there is something odd happening with your machine. I say 'your machine' because in my years here I have never heard of this happening before. It would seem that your flash cache/browser caches are clearing between rounds, because that is the only way that that button gets turned back on, imho.
Good luck, patience with the forum posts... and make sure your Lesson switch is set to "Off".
