You can also use plane ol' Copy and Paste on any image.

Want to use the Chinese language, Arabic, Swahili, Korean languages in a logo?
1. Go to google translate: http://translate.google.com/
2. Type your text into the left and select TRANSLATE (don't forget to choose a language!)
3. Once the translation is made highlight the translated text with your mouse and COPY IT.
4. Paste the text into the working text box in The Logo Creator (It's the small box that always says TYPE TEXT HERE.

Wanna move a bunch of logo elements around together, at the same time?
This won't be like creating a "group" of items like in Powerpoint, but the software does let you temporarily group elements together if you need to move a bunch of em around all at the same time.
Hold down your shift key and select each item, (don't let go of the shift key!)
Then, you can move everything around together!
