Suggestions:
1. Do not take pictures of stuff and turn them into decals/faces.
2. Make sure dacals are the right size and are transparent when they need to be.
3. Be careful on where you post things. For example, this should belong in faces/prints.
4. Try to give pictures whenever possible.
5. If a topic is in the wrong place (like this one) and/or people are flaming you, lock it.
6. Ignore people who mindlessly critizize you or your add-ons.
