I've just been thinking on all of the current working feature that FJ has implimented...mainly: FJ Points, the ability to spend them, colored text, and account permissions.
This in mind I've come up with some cool ideas that would make FJ awesome and encourage more people to strive for getting good content posted and making witty comments so as to obtain more FJ points.
These are the following:
Account options bought with FJ points:
-"Get Out of Jail Free Card" (Extremely expensive and only usable once per account): Nullifies a ban.
-"Unlabeled Paint Cans": These would be similar to the Unidentified Dye's in GW2, in that each one costs the same amount, but they give you a permanent colored text option added to your account, each one being random, and certain colors being more rare than others.
-"Name Plates": Lets you buy alterations to your name in a comment, be it color, font, bolded, highlighted, italicized, etc etc.
-"Item Box": Gives you 10 random items from the FJ items game.
-"Personal Board": Gives the user the ability to create a real Board that is accessible through a list like the channels page and allow users the option to thumb up or down said board, and place the most popular boards at the top.
-"Front Page In a Can" (Extremely Expensive and only usable once per week, and only lasting 24 hours): puts any of a users contents on a new Front Page list consisting of content altered by this item. this list would be directly above the real front page, and would by default only show the newest 5 contents posted using this item. Would be useful for popular OC makers who already have large amounts of FJ points.
-"Thumb Lord": For 24 hours, your thumb up's and thumb down's are worth +2 or -2.
-"Addy's Mention": set the filter for a.dmin to be a randomized list of users who have purchased this item, so that whenever somebody triggers the filter, it will randomly replace it with a name from that list, mentioning the user in question.
All of these items would appear on a list in the users profile, and the user would be able to switch out different name plates/colored text (as these would be permanent), and activate single-use items.
These are just the basics I have come up with, and would take some work on addy's part, but all in all this, and anything else addy would throw in, would not only encourage people to be more active on FJ, but also get people to play his items game to get more FJ points.
