So, some peoples ask how to copy and paste with right mouse button?
This is the WYSiWYG editor and it's allow you more than copy and paste. If you want to copy paste edited text, just click to the button in the right above corner and then at your choise you can do that similar as in your text editor. Another option if you have your own thumbnailed gallery and don't want to upload them directly to the forum you can just drag and drop them to the forum, just mark the thumbnails or pictures you want to post and move them with your mouse to the post/reply message window.

That's it.
