Since your forum has over 30 registered users and over 200 posts, I'd love to do this review for you. I registered under the username 'Reviewer', and once I get a little more understood with your forum, I'll start on the review; it'll be completed in less than 24 hours.

1. Activity :
   Considering the latest post in the section was made today, then that means that the discussion forum isn't dead, and that there's still some juice in it. However, when I enter the section, I find that there hasn't been any latest posts in the subforums since from back in November 2008 and February 2009.

2. Amount of Posts :
   Approximately 400 posts isn't that shabby if I say so myself. It has the most amount of posts than what the other sections have.

3. Icons :
   For the rest of the discussion forums outside of the 'RPG Hall' section, you have animated smilies, but you only have an image. That's not quite intriguing. I'd suggest you should just get an animated smiley like the others.

4. Description :
   

   Welcome to Pokémon RPG! You can battle trainers, catch wild Pokémon, collect gym badges, and much more! You may even become a Moderator!

   
   I think that's a fitting description. But, what's up with the 'You may even become a Moderator!' part? I'd remove that.

1. Activity :
   You have no posts in the first discussion forum, so I suggest you add some posts to it. For the second section, there hasn't been any activity at all since February 2009; that's almost 5 months ago. I recommend some activity in both of those sections.

2. Amount of Posts :
   You have 0 posts in 'Pokémon Flash Game' and 47 posts in 'Pokémon Cheats'. You should either add some threads in the 'Pokémon Flash Game' discussion forum or just delete the whole section because having a discussion forum with no posts at all makes your forum look like it's freshly new or inactive.

3. Icon :
   To cut things down, you have to discussion forums for this section, yet you only have one forum icon. I'd recommend another smiley icon for 'Pokémon Cheats'.

4. Description :
   The 'Pokémon Flash Game' discussion forum could add a little more information added to the description... something like "Wanna play or share some Pokémon flash games? Do it all here!"
   The second discussion forum's description is okay- nothing wrong it.
