I see many people with profile pictures.
And if they post they have some kinda text and pictures under their post.
Please tell me how to do it.
Meanwhile, be cool

Go to User CP which is located in the top left of your screen. Once there click on Edit Avatar on the left, you can choose to use one from a website, or upload one from your computer.

Right under Edit Avatar is Edit Signature. You can add text and links there if you wish, but for pictures you need toriprime.

Oh thank you for your help, it was really useful. About to change stuff right awy.
