Next Monday will be fine.

With regards to what to put... obviously some description of where you've taken your photos, and maybe why you've chosen those locations. Then after that... it's up to yourself, but just as a few suggestions... in some of the previous ones the main points have been a little bit about yourself, and your interests etc. Also, a bit about your ST, how you find it, what your experience has been like with your dealer, and about any mods that you've made.
