There are a couple of rules regarding attachments:
- Unfortunately we can't allow the sharing of copyrighted material because our webhost could be held reliable. (ofcourse we can't check attachments in private messages

- Every SP-Forums member can store attachments up to 200MB (total) in their private messages.
- An attachment can be 2MB in filesize max if I'm correct. (technical limit)
- SP-Forums can't guarantee the attachments will stay up forever, so make sure you have a backup!
For big files we recommend using an online upload website like http://mediafire.com/ or http://rapidshare.de/ . Also, email is still a good way to send files to specific people.
Have fun with the new attachment capabilities and let us know if you have any questions and/or suggestions.
