Well, I know I have gotten pretty disillusioned with putting stuff up here.  Between the low file size limits,  And the rules about file limits, it's very difficult to sell Carrara content here.  For one, the marketplace seems to work on the assumption that all content is as relatively small as Poser content.  Carrara files can get very large ifyou include any decent resolution texture maps etc.  And you can get pretty large files even without them if the model is very complex.  And since you can't use rar files, you can't break up the files into more than one volume easily since just the raw .car file is most of the time larger than the single file size maximum they allow.  If they let you use .rar files, you would have a better chance of getting the files to fit into the limits as long as it isn't too complex and you don't include any high resolution textures.  Then there is the 3 item limit which makes absolutely no sense to me at all.  There simply isn't as big a market for Carrara content so to make it worth it at all, you need to put up multiple files and hope for the best.  You simply can't do that here.  The Carrara Lounge is going to be great when it opens it's store.  Since it's is specifically for Poser content, it should be much easier to sell there.
