Depending on people's numbers the event is now fully booked. If you would like a spot, Line, Arty or Light it would be marked down on the Reserve List which has been added onto the thread.
If I have small for a small line/lines or need a spare light/arty due to regimental attendance issues then whoever is on the top of the list has priority. The list will be reset each week.
Even if you have an already booked event you can add yourself onto this list.
e.g. You have a Line event but want to reserve a Light spot as it may come up. Reserve it. If it is called cancel current event, however you don't have to, others on the list may be takers so if you turn the offer down the offer is passed to the next person reserving that class.
