Can I contact the artists for my request?
Yes, it is possible that you contact the artists directly, as long as they explicitly stated to do so. If they posted that they will not process any requests made by Personal Message, do not even bother. Some artists receive more than 40 requests in as little as 12 hours time. As you will understand, they are busy enough as it is and they will not handle your request for a long time, if at all. Also, please do NOT post a request on the forum AND send a message to the artists as well. This leads to longer queues, more work and less quality/quantity overall. You also have the risk of multiple people making your signature, and this results in wasted time for one or more of the artists involved.
So should I have just sent a pm to a artist in the first place? Did I read it wrong? Like I said not trying to make anyone mad or anything just curious on how i should go about this whole thing, and not get myself artist blocked. Some of the work here is phenomenal.
