Are you referring to time outs and/or IP load errors when trying to post? If you get one of those just click on the back page (not where it says go back but the arrow in the top left hand corner), then refresh the page and when it has refreshed try to re-post. Word of caution, if you are sending a PM and you get this issue COPY THE MESSAGE before you try the above because the message will disappear, doesn't happen with forum posts though.
