beduino,
just use that little paperclip button to implement the attachement to your post (you'll have to implement all attachements to remove the attachement box

)
then hide them using the hide-tags.
Hiding away the complete post is not recommended

Your user want to know what they're going to thank for first for sure

but that's up to you.
Yes, I need to find a more elegant way for attachements, but I haven't enough time

so that'll have to wait
