Always click on the yellow star at the top right hand side of the thread so you'll be notified when someone has responded to your thread and in that way you can follow up instead of you waiting in limbo wondering if there is any interaction amongst our members. If you should back scrolled on some of the older threads you'll notice many are lying dormant because nine out of ten times the thread starter just post their message and no one bothers to follow up so keep that in mind incase you're an interactive person in forums.
If you are unsure as to some of the do's and don'ts in the thread forums just send a request to firstname.lastname@example.org and someone on the admin team or David our Sensei will bring you up to speed. Better to err on the side of caution instead of getting your wings clipped.
