We have a webcomic website in WordPress and we want to implement the functionality to upload web comics from the frontend by users
1) User will create the account
2) He will create the series first (Title, Thumb, Desc, and Category1, Category 2 selection)
3)Once series created by the user it will allow them to add episodes to that series.
4) Episode will contain (Title, Thumb, Web Comic Multiple image upload with order change functionality, desc)
5) Once uploaded it will also editable or delectable in future.
I have attached two screenshots for it.
