Форумы / Cotonti / Support / Can I use structure for a plugin?

I will make a repair log, where the technician can create a observasation or a repair. I don't know exactly what info I need in the registrations, but I think it will include some checkboxes, dropdowns and textarea, maybe the possibility for others to post comments. I'm not sure if I can use pages for this type of task, or what will you prefer???
