A couple of answers to the above posters....
Edi - The magazines do list upcoming submissions in their magazines & on their websites. Just submit through their guidelines & to calls that they are after. Digiscrap layouts have been appearing more & more in the mags - however I think until we see more "advertising" space taken up by digimanufacturers, they will limit the numbers included in each issue (makes sense).
If you head to scrap-source.com website & scrapsubmit.com website you will find that they have a list of what is coming up. On scrapsubmit you sign up & you can actually do all of your submitting from that site - it is very easy (and very succesful

to use) - and they offer this service FREE.
Dand4more - Unless a call specifies that your layout has never been seen on a gallery - you can post them in the gallery until you get the call for that layout - then it is appropriate to remove it (temporarily) until the actual magazine comes out with it in.
