Well, for starters, have you put your Character Details up in the "Harvest Moon Character Details" section? You need to do that first so people know who they're talking to~
Then, once you've done that, you can go to the "Harvest Moon Towns" section and find the right town to live in.
You can either own a farm, be housemates in a farm, live in an inn, be roommates in an inn~
Just go to where you want to go, and click on "New Topic"~
If you need any further help, you cna ask me, another moderator, or anyone in this community~ I'm sure they'd be happy to help~
Have fun Roleplaying!
