Hi to all,
How to attach document file( not only doc,ppt) . All file types video,audio, text and soon.
Is there any plugin for this. Let me know.
Thanks,
Naga Harish Movva.

Not to sound snarky, but have you looked for the answer to this? There's a site admin option that determines what files can be uploaded. It's built in. No plugin needed.

Thanks DeannaS. I will check it.
