I don't see how anyone can appeal when all that is known is the nature of the original charges and the results of the hearing. However, a request for the minutes or something similar would be understandable to see if there are any grounds for appeal. The whole will they/won't they/can they/should they debate and murmurings could be completely avoided in my eyes if the FA introduced some transparency into the proceedings now they've concluded and as has been said on these boards before by having set punishments for offences incorporating the scale/intent involved.
The idea that we "cheated" is a load of tosh. Cheating is to "act dishonestly or unfairly in order to gain an advantage". (OED) We got a small fine for using a Fifa registered agent who happened to not be registered to the FA. Big deal. A very very minor clerical error. We went to the FA initially to resolve the complications with the transfer. By going to them we were acting honestly. Clearly using the 'incorrect' agent didn't give us any advantage, it put us at risk and I'm sure the club would have had the agent registered with the FA (a simple process) had they known he wasn't. I repeat; a minor and unintentional clerical error that gave us no advantage. As for bringing the FA's name into disrepute; I would firstly point out that this in no way affects the playing field. Which means we won fairly! And secondly that I feel this judgement is harsh and expect the club to successfully appeal it. The media gave the FA a bad name, not us. Norwich stole Paul Lambert against the laws of the game from Colchester and almost certainly wouldn't be in the position they are in without him. They got a larger fine than us for that offence. Go and complain to them about cheating. (To Norwich fans; I'm merely pointing out to this WUM that all clubs make small errors, I don't for one second think that makes you cheats, just making a point!)
