Issues for EasySocial Group Code

Morning,

Thank you for your support, I would like to ask for two issues to be resolved for me.

1- I would like users to use a code that is supplied by the group creator to join the group and automatically be part of the group without invitation or acceptance from the group creator.

2- Once the user is part of a group, I would like a menu item which would take them straight to the group that their are signed up to rather than groups because each other with only be signed up to one group.

Please let me know how to fix these issues. I would like to solve it myself and not for it to be done for me.

I would appreciate a quick response.

Thank you
