[xwiki-users] Sending emails with attachments from XWiki page

Hello. I need to make a page where a person could send an email with an attachment to a predefined address. So basically i need a input field that would allow to choose a file to attach, then the file would be uploaded to the server and sent as an attachment. I've found this extension http://extensions.xwiki.org/xwiki/bin/view/Extension/Mail+Sender+Plugin, but it seems to be obsolete. I'm not sure how to store the file before sending it as an attachment, any suggestions? Another possible issue is that i have an old version (1.3) of XWiki. What is the best way to approach this task? I would appreciate any pointers, links and suggestions! Thank you for your help.
