I wanted to donate $5 to Sythe. I went on the donations, and placed a donation and was told that I would be contacted through the e-mail I provided within the next 72 hrs. This was 1 or 2 days ago. That e-mail isn't working anymore, so should I try to re-donate using my new e-mail? Thanks.
Yes, I would do that and I would also PM Mathew, as he is head of donations. Just tell him your situation and I'm sure he will help you out. His profile is located here.
