Attachments now work however now there are real restrictions. We no longer have unlimited space so I can not give you all unlimited storage. Everyone except IBIS clan members can not upload more than 500mb, that should be plenty. If you need more space you will need to remove your older attachments. Limits have been placed on some file sizes now but that is more to avoid some sort of dos attack and should not effect you in any way.
Attachments have not been turned back on and you should be able to use them exactly like before.
