I have done one or two commissions for a fee and one or two where it was a donate to the guild job which is my kinda free cos there's a $5 min donate which is next to free ain't it ? Generally like said I would do it for the CWBP generally or I might do it to try out some effect where I would try it anyway and being free or next to then if it goes wrong and does not give the desired effect then its not like anyone is hurting from it. Many of the challenge maps at least last year were with no remuneration bar the shiny icon next to your name. We do free maps all the time. Only time it really bugs me is when the request is littered with "I want" so and so like were doing this as a job. My personal opinion is that if the request is specific then it ought to have a little something in it for the artist or guild and, as said, finding one of the finished maps and getting permission is likely to be the better, quicker, option. Kudos to anyone who makes maps for free - its cool and yes it might prevent a potential commission but that's life. The Gimp is free and preventing Adobe et al from getting greenbacks. We all like free but sometimes there has to be something in it to keep the pro's doing what they do best. Which is why I donate a little to the guild and some other sites - which reminds me that I need to add some more to the pot again as its been a while now.
