A code that would let staff place text in a post that only staff can see, like a post note only for staff

No matter how this is done, it wouldn't be possible to hide it completely. People would be able to see it by using View Source, or by disabling JavaScript.

If you're happy with that, I'll code it for you!

lol the only way is can be done in a half way decent manor would be to have it hard coded, with JS and PHP

If the members do not know about the code then there will be no problem with it being just JS based

there is those that disable JS to increase load time. Darkmage does it all the time, as an example.

I actually like this idea.

*Moving to suggestions*

I can't promise when or even a definite "yes", but I will seriously consider it next time I make a change to the UBBC parser. Something like:

Sweet Ross

This will be included in our next batch of updates. It will support tags for:

[staff] - Content is only shown to staff members

[member] - Content is only shown to registered members (including staff)

[guest] - Content is only shown to guests and (to prevent abuse) staff members

I've included the member and guest ones as they can be a good way to encourage guests to register. eg. Only showing a particular image or link to members. The staff ones could also come in handy for support issues.

The tags would be available for any member to use in their post. I've included the ability for Javascript/CSS to be able to change how these notes display and show where there is a hidden note.

Nice Ross, when is the next batch of updates?

I've got a few ideas for these!
That's awesome.

Very cool, Ross.
