How I create interactions with people is by doing the following:
1) Find excuses to talk to as wide a variety of people as possible. This might mean being fearful of a magicker and expressing that fear quite visibly such as with furtive glances, shaking hands, even saying hello when you think the magicker is looking in your direction.
2) Find things for people to do. If you see a 'rinther, ask them to buy spice. Or ask them what the latest word is in the Labyrinth. Ask them to tell you who other criminals are. Knowing who the local criminals are can help you buy stuff on the cheap. We all value rumors. It's why we always type "look board rumor" and then read them. Asking other people what rumors are on boards you can't see gives you that information. Don't know everything there is to know. Instead of risking life and limb, offer to buy food from new hunters on the cheap.
3) Find out what other people are doing. Find ways that helping them benefits your and then help them. But always demand a price or benefit to your character that they are willing to part with or provide.
4) To create plots, give yourself goals and try to involve the widest range of people possible. Do as little yourself as possible, potentially only giving yourself the goal of raising funds to pay everyone else (which can be done by asking for favors for other people or via coded means).
5) Give yourself one meaningful flaw that will be counterproductive to your efforts. And then do your absolute best to hide that flaw while still roleplaying it appropriately.
6) Remain true to your character. Don't break character just to involve others or create plots. If your character is terrified of the desert, remain terrified of the desert. Only ever enter it if you absolutely have to. But also be willing to make minor tweaks to your character as necessary. But only if it's truly important.
7) Don't try to generate drama plots. They'll happen naturally without any effort from you. They're also the lowest of low quality plots.
Communicate with staff as regularly as they want you to. Once you start doing things that involve other players, shoot them a quick report and ask them how often they would like you to update them in the future.
None of the above requires staff support. By increasing the amount of interactions you have, you'll start getting involved in other people's stories. As you start setting goals for yourself, you'll naturally start to generate plots that other people will enjoy helping you with. The more people enjoy working with you, the more they will interact with you and the more plots will naturally generate.
Also none of the above rules should be followed all the time! Even the ones that say "always". You follow every rule above to the letter, you'll burn out and get bored. Pick and choose which ones you follow at any given time.
One final note that's a big one: The more fun you generate for other players without staff support, the more likely staff will be to provide assistance for plots that do need their help.
