No apologies are needed, ask questions, let us help you, that's what we are here for.
OK, so NO staples in the forms. Use a bulldog or a binder clip to hold everything together, but no staples. Or use paper clips for smaller sections.
Put your pics in a separate envelope so they stay together and don't flop around. Label them with who, when, where, what and why information (e.g. sponsor and applicant with applicants parents at X restaurant on X date to celebrate sponsor's birthday). I actually arranged mine chronologically, so you could follow our main events through pictures...from when hubby would send me pics from his webcam, to when he arrived, to when he met my family, to when we got married, to when we had our honeymoon, to when we had various dates for my birthday and just before he left Jamaica. Just ensure they can tell from the label who is there and what is going on and why and when.
Two things that really helped me: tabs were my friend. I arranged my evidence and forms in sections, and labeled each section with a tab. So I had tabs showing where you find sponsor's forms, applicants forms, chat logs, telephone bills, financial support, letters of support from family. And I bought a plastic document folder to put everything in when I was done. It closes with a little cord, and is very sturdy and waterproof.
