Message from the yacht

I have just received this message via the communication known as semaphore from Mike Morgan's yacht in the bay:

Could you reprogramme the matrix //2468-ar lan y mor-90// as from the original selection. We need to check who is available.

Anyone who can't make 6pm from the original team please contact Dan and if others are, also please tell Dan.

Looking forward to our adventure to Penclawdd

Ave Daniares! Morituri te Salutant.
