Etiquette?
Well when someone posts the free trial to ace's high or fighter ace in the WW2OL forum no one tries to beat them away with a stick.. They say, "Thanks for the info, I think I'll give it a try, but it might not be my cup of tea anyway."
It's not solicitation, it simply makes sense that some of you would want to try this bombing for yourself - so you can chose to give the 7 day gigex trial a go or not, whatever, you're choice.
