Dates definitely 2-3-4 April.
The organizers are still finalizing the program but I understand that this year there will be mushroom experts coming from some of the UK Universities also events will be increased to include tours of Cadianda and maybe some other places of interest. One of the organizers was telling me yesterday that they are trying to arrange for one to a firetower from which on a good day you can see Rhodes. Before anyone asks I do not know where this is yet.
