Should be there.
Can anyone except me confirm that the Permissions are there?

is needed in all situations to update the bitfields of permissions...

it's all showing correctly from here though!

thanks KirbyDE to have move this to permissions!!! (my request!)

;)

It's not necessary - the Product install Code rebuilds the Bitfield Cache automatically (well, at least it should).

3.5 RC2 here. Just installed as a product and uploaded the xml to the correct place (it says /includes/ so thats where it is).

Seems to have added the plugin fine, but I DON'T get the usergroup permissions as described.

No, bitfield_siglimits.xml must be uploaded to includes/xml!
Edit: Just noticed that it was in the wrong Folder in the ZIP ...

next feature: add all these details in a block like the "Posting Rules" in the "Edit Signature" page... so users will be informed of their restrictions...

this is not really needed, just a neat new feature!.. :)

Updated, details see first Post.

I have a very heavily modified forumrules already. Is there a way to have it only show up on the edit sig page in it's own box?

It shows only on profile.php?do=editsignature ... and if your Template is heavily modified, chances are it won't show up at all :D
Anyway, you can always take a look at the Plugin and modify it to suit your needs.

Thanks Kirby!
