Uploaded design post. I up loaded a design and now someone wants different formats. Can I alter the original post or do I need to make a new one ?

Yes, you have to a make a new post. If you have several formats ready you can put them all in the same post. You just can't add to the old post. Don't worry about it. Go to the old post and put the link to the new post in a comment and then put the link from the old post in to the new one in a comment. Use the "add Link" box. That way people can find their format no matter which one they see first.
I love the little duck!
You can also refer the Cuties to the software so they can convert formats themselves. I used the links at the bottom of this page.

I can't remember, but I'm thinking you will have to post the same thing in a different format. A lot of the DBC will post all they can in format, some can only do the one. I have a converter so I take any. hehehe. It's an adorable applique...You can also contact the person requesting it through PM and get her e-mail to change it for her if you want. It's up to you.
