you can go back and edit it - for the pic atleast, not sure on the wrong section...you might need to take a ticket at the help desk for that - but it will still come up on the 'new items' list anyway
do you know how to resize a pic on your computer?it needs to be under 100kb. thats what i do, then i click on 'browse/upload pic from your pc' and put it up that way. theres also a host it somewhere option, i couldn't figure that out...also needs to be under 100kb..
