The editor is a WYSIWYG (what you see is what you get) style editor, but I've noticed that what you see in the editing window is not always what you get in your post. Can be frustrating, if you want to exercise fine control over the look of your post.
I've found that clicking the
button above the editing window will give you plain text, and will include the BBCode as plain text, so you can see what makes your post look the way it does. That makes it easier to see what may be messing up the appearance, if you have a problem with it. Some people may be more familiar with seeing the BBCode than with the default WYSIWYG. (me.)
Also, if you copy and paste from a website (or some other documents) the editor will preserve the original formatting, including links to images. That may be what you want, but if it isn't, and you want to eliminate the original formatting, clicking on the
button will do it. It is considered rude in the webmaster community to "hotlink" to images on other people's servers (and they will sometimes swap the images to something nasty, to retaliate), so it would be nice to take the time to put the image on tinypic.com or some other image posting site if you include an image pasted in from another site.
Tinypic will let you post images without signing up for an account, and if you're like me and already have 10 zillion logins and passwords to keep up with, that can be a blessing.
A note about using tinypic:
Images and videos is in your account will not be removed. Images and videos that are not associated with an account are kept until they have not been viewed for 90 days. After 90 days, they may be removed.
