Comment on Beall’s List of Predatory Publishers 2013 by Ijin

Any of you have an idea of the Germany-based Scholars’ Press? I have been sent an email from them in which they said they are interested in publishing my PhD dissertation. Now that they saw my work (very drafty one according to me) they renewed their intention to publish it, and they sent me the link to register saying that this “opportunity” is going to last only 15 days (7 days now). All this sounds suspicious to me and am not sure which moves to take. Any suggestions?
