I have posted edited rules in the very first post on this thread, and would like to draw everyone's attention to the new rule 6;
6. End of the Line: When at the 3rd station from an end point, if the 2nd station is not posted within 3 hours, then 20 points are taken from the leg total. If no posts are received over 6 hours, another 20 points are taken from the leg total.
e.g. We are at Bayford. We have already used Stevenage and so the end point is Watton-at-Stone. If Hertford North is not posted within 3 hours, 20 points are deducted from the leg total.
