* Now groups are displayed in drop down list view
    [Note: It was not the issue with existing groups] 
```
modification in;
* __init__.py  --> Changed RedirectView to HomeRedirectView
* home.py  --> changed group name as user to user id
```

* Profile Pic notification for already uploaded images 
```
modification in : 
userDashboard.html  --> Added condition for already uploaded images
