This modification has been withdrawn.
vBulletin 4.0.x and 4.1.x are no longer supported.

The feature is already built into the core vBulletin 4.2.x code.

This is a current version of the popular modification, originally developed for the early 3.x series by Xenon.

Basically, if member posts in a thread where they were the previous last poster, then if the conditions are met, their new post will be auto-merged into the previous post instead of creating a new "double" post.

A number of options are provided ;

Time Limit - if more than xxx minutes have passed since the last post, no merge is done.

Timestamp Spacer - if enabled, a timestamped spacer is added between the old post text and the new post text.
Other spacer choices provided are no spacer, a default, or a custom spacer.

Spacer Colour - allows you to set the colour of the spacer between merged posts (if one is enabled).

Post Timestamp Update - if enabled the newly merged post will have its post time updated to the new time, otherwise it retains the time of the original post.

Usergroup exceptions - Allows you to exempt certain usergroups from the doublepost merges.

Forum exceptions - Allows you to exempt certain forums form the doublepost merges.

IP Address Check - Specifies if the poster IP should be checked, if enabled, the post will only be merged if the user and ip address are the same.

All settings are located in vBulletin Options > Doublepost Prevention.

To install just unzip the XML and import into vB using the ACP Product Manager.

The only way we were able to stop the double posting was to disable the QUICK REPLY . Since then, we have not had double posting.
