The boards are most certainly a helpful place for people get into stories, but if they aren't giving you the results you desire then take matters into your own hands. Talk personally to people you game with currently. I'm sure at least one of the players that you rp with would be more than interested in getting into something exciting. It couldn't hurt to ask, right? Also try to change it up a little. Rather than joining or starting a new guild, add the drama you want into a char that you already have. Don't look for other people to do it for you, and use inspiration outside of the places that tend to follow that cliché trend. Avoid movies, popular books, and the tv for your ideas. Find something that you think is interesting and build up a plot around that. You might be amazed where they come from if you keep your eyes and ears open for it.
Another tip for a storyline; nothing is ever perfect. Playing in a world of sunshine and rainbows might be amusing for a while, but it grows old quickly. Remember that supporting npcs do have a mind of their own, and not all of them are going to jump at the chance to praise what you have done. Sure you killed that pack of wild dogs trying to attack the village, but did you demolish the farmer's field and only livelihood while you did it? Try something where your char is the under dog, and struggle to reach your goal. Mind you, that doesn't mean running a week long game where you start out abused on the street then suddenly become king admired by all. Good drama and rich plot, in some cases, can be made better by letting it simmer. The lulls can be used as down time to let other players relax, or to help heighten growing anticipation.
If all else fails, talk to the leaders of the guilds you are already in. I am sure they would understand, and they might use you to further their plot along. Keep in mind most of these plots involve many people, so give being a supporting character a chance. The one who catches the hero when he falls is just as important as being the hero and getting all the action. It by no means makes you less of a player, only a more flexible one. You'll get your turn in the spotlight, and more respect for being able to allow other people to shine for a while too.
