@Lakot: As the rules have only just been updated (due to a member posting a request in the comments feature of the gallery) you were not to know so not problem
@Zac: You are right, there can be a fine line between requests and suggestions...
Things to think of:
1. Never ask a certain artist to draw a picture unless they have said they are taking requests
2. "I want" gets you banned :P (just kidding, but do it too much and you will get banned)
Examples:
"I would love to see a pic of Sara from Love Hina getting spanked"
This I would class as a request. No thought has gone into it so its just a case of "I want to see this character spanked"
"Please draw sara from love hina getting spanked"
This is definitely a request
"From the moment she came into the anime, Sara from Love Hina was a brat! I think its a real shame Keitaro never got to even start that spanking before Naru punched him through the roof :P. I think that Sara over Keitaro's knees with the rest of the cast (See exceptions below) lined up with implements of their choice would be pretty funny. To spice things up a bit more you could throw in either a nervous looking Su (I swear she needs a spanking almost as much as sara) or a very red bottomed Su in the corner. I can't see shinobu as a spanker - she is far too shy so maybe she could be comforting the either freshly spanked, or about to be spanked Su..."
This is definitely a suggestion. (It took me a while to think up a setting etc) Notice how there is a lot more information than just a character name - if you don't know why a certain character should be spanked try starting a thread asking other members what they think in the "Spanking Chat" section of the forum - you might be surprised at some of the replies you get.
