If there a problem with a post made with copy paste, there is no way to edit the post to fix it and is not possible to moderate from administration. is there other way to edit it and fix it or even delete it ?
We don't understand correctly the copy past part, please clarify it. However, the user must have the above permission you mentioned to have the right to do that.
If you copy paste an article form another site to a post, because of special characters destroyw all topic and there is no way to edit it and fix it
And remember that in our forum there people that they dont know what is an editor, here all are familiar with all these, in normal forum 90% are not, you can give them help for things they care not how to copy and use an editor.
