New in version 1.6: This feature is available since Weblate 1.6.
In default Weblate setup, everybody can add suggestions and logged in users can accept them. You might however want to have more eyes on the translation and require more people to accept them. This can be achieved by suggestion voting. You can enable this on Subproject configuration by Suggestion voting and Autoaccept suggestions. The first one enables voting feature, while the latter allows you to configure threshold at which suggestion will gets automatically accepted (this includes own vote from suggesting user).
Note
Once you enable automatic accepting, normal users lose privilege to directly save translations or accept suggestions. This can be overriden by Can override suggestion state privilege (see Access control).
You can combine these with Access control into one of following setups:
To improve collaboration, it is good to prevent duplicate effort on translation. To achieve this, translation can be locked for single translator. This can be either done manually on translation page or is done automatically when somebody starts to work on translation. The automatic locking needs to be enabled using AUTO_LOCK.
The automatic lock is valid for AUTO_LOCK_TIME seconds and is automatically extended on every translation made and while user has opened translation page.
User can also explicitly lock translation for LOCK_TIME seconds.
