Actually, my thread will not disappear, it is a bonus of being the mod of the section, I stickied it and can edit it as many times as I want, but I know what you are saying.
The only problem right now is, most people see portfolio's as something to display large art, but how many people have made say 10 pieces or more? If we did have a portfolio sub forum, there would be a minimum amount of work needed before posting one.
