With regards to payment, I would point out that everyone here has won or is hoping to win a contest where the monetary value of winning is in the thousands of dollars, so I think it's safe to say that everyone here would rather get paid for their work. Also, self-pubbed illustrations don't hold any greater weight on a resume than simply putting up an online portfolio, unless by some miracle the project becomes wildly popular. Regardless, the fact that you're asking for unpaid commissions is just the cherry on top, not the real problem.
On another thread, we have been questioning the appropriateness of people creating an account for the sole purpose of soliciting work (paid or unpaid) from regular forum members. This is a forum primarily for discussing the WotF and IotF contests. If a regular forum member posts about an unrelated project, that's a perfectly appropriate digression from the main topic, since we know each other and are to some degree invested in each other's careers. If a total stranger with no interest in WotF/IotF posts about an unrelated project, it's an intrusion.
