We have a standard message which accompanies the invoice sent to members whom we're asking to renew their membership.
We need a similar message for members whom have singed up for a membership but chosen the "pay later" option. The invocie text (at Medlemskap/Zynatic/Faktura) can probably be kept as is.
Keep in mind that they already get the //Välkomstmeddelande// by signing up.
