First of this is to help people who are struggling to get sigs and avatars working on these forums. Also atm the forums are still not working for sigs linked from places like imageshack and such.
First off you need to go to your settings, at the top of the pages.
The to Edit signature on the left side of the screen.
Cycle down to the section named Signature Pictures
Now because the forums are not allowing linked sigs, we have to use Option 2: Upload image from your computer. Here you will need to find the image you wish to use as your signature and press the ok button.
Now you need to Press the "Insert Signature Picture" button. By doing this it should place the "[SIGPIC][/SIGPIC]" into the signature box an therefore giving you your sig.
This is very similar to the Signature walk-through i just gave.
You go to the Edit Avatar.
Then go to Option 2: Upload image from Computer
Find your image and press OK.
Then Just Click the Save Changes button in the bottom right of the box.
If i get time soon i will add some pictures to this post, but it is if i get time. If you still need help just asking on my profile page and i will try to help. Hope this helps some of the users who are Struggling atm.
NOTE: THE SIG/AVATARS WILL ONLY APPEAR ON NEW POSTS, NOT OLDER ONES!
