That`s happened to me too, before.
Yesterday, after about 9 posts I received a message of being only alotted 4 posts/day and that I was over my limit....hence the test post...which went through anyway...then I was cut off.
Who knows why these boards get tweeky. Everything`s back to normal today.
I wouldn`t sweat it. Afterall, we were up today on some good news and all those ``dedicated`` longs didn`t have much to say. lol
