Hello heyheyhey,
Your profile is your own, you can include as much or little as you like. Some include a brief description of their interests in the
About You section while others link their Requests Thread(s) and/or Journal. It's worth noting that while RP interests can be listed in the
About You section, advertising or seeking RP in status updates is not allowed.
Most members like to customize their profile picture.
Here are the instructions if you would like to do so.
If you're looking to attract potential RP partners, I recommend creating a Request Thread as opposed to relying on members to check your profile. Retrojapan made an excellent template that I think covers most of the relevant information members are looking for when searching for RP.
