Ok Since this forum board is a little different i will post on how to upload an avatar to your profile.
Steps
1. Click on your profile
2. On the right top hand corner you will see: Information | Preferences | Signature | Avatar | Watched topics
3. Click on Avatar and Upload it
The same goes for signature:
1. Click on your profile
2. On the right top hand corner you will see: Information | Preferences | Signature | Avatar | Watched topics
3. Click on signature and type it up
4. The signature will not show up until you have made a new post
