Guiders need unique email addresses to accept an invite. If you use a shared inbox, please consider creating an alias email for this inbox, or alternately, using a different email altogether. Certain email providers like GMAIL also allow you to create alias emails by adding a "+". (For example, [email protected] [email protected] will be the same gmail account inbox, but will allow you to create separate ePACT accounts.) Please update this directly in Girl Guides's IMIS.
