I haven't come across this-- are users other than the author able to quickly suggest or add tags to posts? It'd be a nice community effort thing that promotes engagement.
Not too sure what you really mean here. Would you mind elaborating more on this please?
If you go on Quora you can easily add topics to questions and the original author is notified of these edits. They can then choose to keep the edits or revert them.
If not already a feature, I think it'd be useful if registered users can add onto existing tags on blog posts.
I don't think this makes sense as a feature in EasyBlog but perhaps it's more suitable for EasyDiscuss. Please feel free to post your feature requests at http://stackideas.com/voices/easydiscuss
I'm using the feed import feature to curate content. I'm manually adding tags, but I'm just one person. People read the article and think it could use more tags, or tags need to be changed. Perhaps a user could add their own tags, and a moderator or or original poster can accept or decline changes.
I think wherever tags are involved, community involvement would be a benefit.
It would be best if you can submit a feature request regarding this in our voice page -> http://stackideas.com/voices/easyblog, so everyone else could vote for it, the more people request on this, and we will priority consider it.
