Hello. I noticed this earlier and moved it out of view for a while, just my sense of humour I suppose.....
In response to your questions, shares in planes are often allowed on this forum, encouraged in fact. For Sale items are positively discouraged, we don't want the forum to end up like ebay now do we and I often have to remove threads that are selling all kinds of things, mostly used ppl equipment but we just can't have stuff like that cluttering up the forum.
I had a complaint last night saying your thread was advertising. At the time, I thought I would leave it up for a few hours so that others could see it, as you say you have paid for a title and I am quite lenient regarding allowing links etc so I let it stay for a while but after I logged off it was moved away by someone else.
The OBA threads have nothing to do with this they have their own place in the wannabees forum.
I couldn't agree more with your last statement. Unfortunately, this does not always happen. Could be a number of reasons why mods don't do it, I do it whenever I can, don't forget we do this in our own time, we do what we can, when we can and if I have only a few min's taking a quick look over breakfast or something then I won't have time to reply until I return home. With some mods this could be days.
I hope this has cleared a few things up for you.
