The quota is only a temporary thing. It can be easily increased for any poster who finds that they have more to contribute than the 3 posts allows,lol. However it is a very nice way to keep new posters from quickly disrupting the place to any large degree.
I see that more of GMXX crew has started to sign up here, perhaps this board will be an asset for those of you who wish to converse somewhere you can actually hear each other.
