I’m not sure, if someoneelse already answered you, so you might get this twice. If so, sorry :)
Of course you can still submit. Just scan in your signature on a white paper, and send it to our e-mail. We will then manipulate it to the size we need it in.
If you have more questions, just check us out on facebook (the group 150,000 signatures) or our forum (signatures.tyrope.nl)
