Hypnagogia must be right, apparently there are no real size limits. Yet I often run into nasty problems as I try and download from ShareCG anything larger than 20 MB - at some point (usually towards the end, must be Murphy's law...) something in the connection goes awry and all I get is a fistful of nothing, an useless .part file. Took me 7 tryes, plenty of time and quite some stubborness to get hold of a 56 MB file I absolutely didn't want to give up :-(
OK, must be just my crappy web connection, but, alas, I'm helpless there - and like me how many others?
Hence my heartfelt pledge: before uploading gargantuan files do think also of us peones and consider breaking them down to smaller chunks, will you?

Thanks :-)
