Are there special instructions we should be aware of then???

Yes Cap'n

The clue for 11 across is normal, with a normal solution to be entered in the grid normally. All other clues consist of two cryptic clues, side by side. The two solutions they generate are to be entered side by side in the grid but cyclically, starting anywhere in the designated space. The required starting points will be confirmed by crossing letters and by the fact that, in the 26 squares around the perimeter of the grid, all the letters A to Z appear once.

Thanks again, Mamya, it's getting to be a habit. ;0))

worworcrossol, please take note, if you want answers, please supply the full info.

Thanks, Mamya. I didn't give the long instructions because... I was too lazy!

[Mamyalynne]

No worries, if I need a cuppa after reading instructions then it's not the crossword for me.
