Yes clouie, all information is required. This is particularly important when ID information is needed. If sponsor programs have paid you via Epassporte, check out the sponsor sites and grab specific amounts you were paid. If you cannot remember dates/amounts, state what would be a reasonable estimate and why you can't be specific.
The "source of funds" would be prepared by you, and if you are webmaster, assume the source of funds to be from a number of sponsor programs. Simply list the names of sponsor programs as being the source of funds. If there is a need to provide detailed information on sponsors, it's easy to do screengrabs from sponsor sites showing amounts paid via Epassporte.
The proposed use of funds - that depends what you are using the funds for. If rational amounts (under $10K), this could be rent/mortgage, living expenses etc. (The bank does not need to know the cost of dog food

) If over $10K, there will be additional paperwork needed.
If this still looks vague, just explain the reason, for example, that Epassporte has closed down and you do not have access to statements etc.
Hope this helps
