I went ahead and put together a simple product, which I have attached, and which works in vB 3.8.9 and vB 4.2.x.
There are settings for:
- Enabling/Disabling Product (you must initially enable the product)
- Selecting Destination Forum For Changelog Thread (If none is chosen, then the forum used for reported posts will be used)
- Thread Title
- Report Format
The first time a username is changed, a new thread is created, and then after that new posts are added to this thread for each username change.
Please let me know of any issues and/or if you want any additional features.
