I would like to propose a new stack that will only deal with questions related to WordPress plugins. This isn't for WordPress plugin development questions, but rather, for questions related to setting up and/or using specific WordPress plugins.
The reason behind my suggestion is I asked a questions regarding a certain complex setup using iThemes Security, but it was put on hold with the reasoning that the question is off-topic because wordpress.stackexchange.com is only for questions that are for pure WordPress development, not for third-party plugins. After further discussion, it turned out that this was an issue that the WordPress moderators previously discussed, going back and forth, without reaching a final firm conclusion.
However, I do believe that third-party plugins (and themes) play an integral part in WordPress, and therefore questions about them should not be put on hold immediately.
Therefore, I would like to suggest that a new stack be created, could be named wpx.stackexchange.com (wpx = WordPress Extensions), or could be named anything you like, that will deal solely with questions regarding third-party plugins, such as WooCommerce, W3 Total Cache, iThemes Security, Contatct Form 7, or any other plugin. Again, all questions in that new stack will only be related to WordPress plugins, with some available tags being the names of those plugins. Restrict questions in that stack to plugins-specific questions. Those should only be about plugins that already exist.
If there are questions regarding plugin development, then those should be asked in wordpress.stackexchange.com, keeping it as it is, for issues related to WordPress development only, and not including any question related to third-party plugins.
What do you think? Your input is greatly appreciated.
