So I want to know something about my NX50 camera. I go to the correct forum (I think), but there is no option to post a new message.

http://community.sony.co.uk/t5/How-Tos-FAQs-Cameras-Camcorders/tkb-p/ca_en_5

Is it possible to ask "How to" questions via this forum, and if so, where should these be posted?
