Hi Jogamel - The letter before the slash should be written to the left column, in which that word occurs, and likewise, the letter after the slash, at the top of the column in which it occurs.
Then, by dividing the first two surplus solutions into sequential pairs, you can get grid references, allowing you to identify the venue and time! LOL
I have also found half of the present, by cyptically finding kisses in the grid, but I cannot yet, and hopefully before I am certified insane, deduce the other half of the present from the fourth surplus word.
Jesus wept, any help appreciated!
