Hello, MeganXAlij.
I'm assuming you're fairly new to roleplaying, so I hope you take this as friendly advice. Forum roleplays work differently than they do in shoutboxes. For starters, a written plot is needed, even if it's as simple as "Megan has left her family's pride and decided to create her own. Will she succeed?" Granted, that's far from perfect, but it gives a starting point for you to either add or subtract additional details. Remember, a plot with detail is usually one that sparks interest. Second, there needs to be some sort of bio form for potential members to fill out. This allows not only you but others see what type of characters may be joining, and bios are also a good reference tool during the roleplay (Such as, is this action realistic for the character's personality/history? Or, what does that character look like again?)
Plot and bios are the backbones for any good roleplays. Also, if you ever decide to read up on them sometime, here's a link to Black Rose's guide
/board/rose-s-roleplaying-guide-t34481.html (I personally find it very helpful.)
Anyways, hope this helped, and good luck!
