can not change the group type - it has to be by invite only.
do you offer customization of your scripts? if so how much would it cost me to have it customized to my needs? that is I want the parainvite to send invitation to join the group not a link to group show less

what do you mean? my users can send join request to groups show less

thank you for your response
I used sharing module with group scheme but it dosent send group invitation - it just sends link to group page - my groups are " by invite only" type so if I click join the group link from email invitation it goes to the page I can not see and I see only 404 page
can this be fixed so paraivite sends actual group invitations? show less

Oh , I just check it and figure out what is the problem - so when sending invite to join the group if the email is already register then it just send internal friend request and no email , and its request to be friend not to join the group - thats the first problem
second is that when email is not registered then it sends email with invitation to join the group but the link to the group redirect you to registration page and after registering you are still no member of the group you were invited to - can we fix that? show less
