Well, I saw that you admins mentioned that you needed more ways toget HP's than advertising, so here comesa few, all of which can be tweeked and such, they're just suggestions ^^
HP's for completed threads Whenever you have really finished a thread, and it must be like.. 5+ answers per person in the thread and like, say "Finished" at the bottom or something, you could put a link in a special thread with that thread, showing that it's finished and you get.. maybe 5 HP's per post you've done in it? (Apart from what you have gotten from actually posting the replies of course.
Raising the amount of HP's for advertising This way, people wouldn't need to advertise as many times, right?
HP's for starting a thread A roleplay thread of course, open or reserved for others
HP's for being in a herd with a horse A small amount that you can collect every week for the horses you have in herds, this would also encourage people to get their horses in herds. Although you would need to reply to a special thread once every week to get those Hp's.
Opening the lottery again? Obvious, right? xD But I think you guys mentioned that you mean to get this up soon anyways.
Getting HP's for breeding A small amount of HP's for breeding maybe? Wether or not it's by force or willing.
Just suggestions and I know that most of them will probably be rejected, but thought I would just get them up there ^^
