WWI diary going digital - Hilton George Olliver

I didn't realise once target was reached donations would still be accepted. I can return the funds that came in later, or reserve them to put towards possible costs of online storage (the file will be huge), possibly getting a hard copy printed (I'd like to transcribe what I can in the future) or making digital copies to CD for distribution. What are your thoughts? I can close the page now the target is reached or leave it until closing date (in 12 days) ...I am also happy to put extra funds aside for other heritage projects.
