We run an After the Deadline server for your personal use. For commercial needs, we recommend using our free server software.
Would my blog be considered "commercial" if I had some Adsense and affiliate links? It is not even generating any income yet.
Should I really get the server software? would that be my own PC? is this really going to work ? I mean I just want to get this AtD installed on my blog and help me write.
