Reviews

A review is a serious examination of a person's experience with an extension which is presented on the Joomla! Extensions Directory. Praise, difficulties, or comparisons with other extensions are all valid parts of a review, including the reasons why.

Reviews must be honest, unsolicited and uncompensated.

Self promotion, by creating unnecesseary links to personal/business sites, shouldn't be part of a review for an extension.

A review is not a location for requests for support. Support question should be taken to the Joomla! Forum or the developer of an extension. Please stay courteous and don’t use any offensive language. After finishing, a review will be accepted by a member of the Joomla! Extensions Directory team if it abides by the guidelines.

There is a possibility that a review contains a statement which is inaccurate. For example, this can happen if a new version of an extension fixes an outstanding issue, or if the statement isn't valid for another reason. We hold the right to withdraw a written review after it has been put online.

If you feel that a review contains incorrect information, please contact one of the moderators of the Joomla! Extensions forum. The Joomla! Extension Directory members will not moderate reviews, unless this is done in agreement with the reviewer. If a review poses a problem in some way, the review will be pulled offline. A short investigation will  follow, both parties will be contacted by a member of the team. After  investigating, it is both possible that the review is being kept offline, or that the review is put online again.

In no circumstances will personal information from Joomla! Extensions Directory members be shared with 3rd parties, unless this is the direct wish of said member.

Voting

• A user account can only vote once per extension. Please do not vote until you've used an extension thoroughly, making sure you have configured it correctly.
• It is not allowed for a any person to solely rate an extension to artificially inflate the rating or vote count.
• It is not allowed for the same person to have more than one account on the Joomla! Extensions Directory.
• It is not allowed for an extension developer to give negative votes to other extensions who are in competion for rating ranks, or to submit votes to extensions which offer similar functionality.
• An extension developer, his family and\or colleagues are not allowed to vote on extensions from that developer.
  
• If any of the above three rules are broken by an extension developer who has extensions on the Joomla! Extensions Directory, all extensions owned by the developer will be unpublished from the Joomla! Extensions Directory for a time set by the Joomla! Extensions Editors (starting from one month to inifinity).

Any queries about these rules should be made in the Extension Directory forum

Extensions and forks 

An extension that is derived from another extension will only be listed under the following conditions:

• The original extension license allows this, or the current developer of the original extension has specifically authorized it if the license doesn't.
• The extension is renamed, so it's clear that this is a separate project.
• A new versioning scheme, so it's clear that this is a separate project.
• Extension will be actively developed on.
  

 If the original extension is listed on the Joomla! Extensions Directory:

• It will only be allowed when the extension has been changed by adding new functionality.
• Development of the extension follows it's own path, and will not be based on the original extension after listing.
