i guess I need to expand my explanation a little. What I wrote was more concerning the downloader, not the uploader.

Starting with a saved .xls file on your computer save a copy of it someplace handy in preparation for the upload. As was suggested, I have my computer set to show all file extensions. I rename this file's extension to .jpg using the right-click menu(this is occuring outside of excel, I don't think you will be able to do the rename function inside XL). This file can now be uploaded using the forums attachment feature.

Forum users would then right-click the attachment and select the save-as function. It can be renamed back to .xls right now or after it is saved to the hard drive.


PS. I am kinda between boats right now. I have been sailing a Nacra 5.2 for years and am waiting for a Blade to show up in the next week or so.

I have attached the above linked boat file using this method. This worked for me using Internet Explorer. Using Mozilla Firefox, the save-as function was trying to save the file pointing at the attachment, not the attachment itself.
