TOPIC: Can anyone help me?

Can anyone help me to make signature and tell me how to place it?

If you don't want to make your own signature, there's some threads where people are making ones for free. Here are 2 examples:
Am1og
spodermon
Make sure you use the full template given in the thread if you want one made from one of these ^^
If you want to make your own signature, I can't help you.

Once you have the image upload it to Imgur

To use the signature, go to Edit My Profile --> Profile Information --> Scroll down to the bottom and there's a signature box.
Then type:
If that doesn't work, you need to put '.png' at the end of the link.

I hope this helps!
