Welcome to RPG!

If you're only looking for those few specifics to RP, you should probably create a thread advertising what you want here in the [url=https://www.roleplayerguild.com/forums/16-1x1-interest-checks]1x1 Interest Check[/url] section. Just hit "new topic" on the right side of the screen. Of course if you were wanting a group RP instead, the other interest check sections work too. The thread you make in an int check section will appear on the main page's side bar, which will give it some exposure. Hopefully you have good luck finding a partner that shares your interest, but don't be too discouraged if you don't at first. 

Advertising off-site RPs (including discord RP) is not allowed on this forum, but you can RP via [url=https://www.roleplayerguild.com/me/convos]PMs[/url] which are private or in a public thread in the corresponding roleplay sections. I'm trying to think of what else to include for a new forum user, but I think most of the features are pretty intuitive especially if you aren't coming from a different forum that uses slightly different style. 

If you have any specific questions about the site, feel free to ask! Most people would be willing to help you out.
