I recently (ie. today) set up my own wakaba imageboard and I was wondering how to do some things. Now, I'm not sure if these things are 4chan only or if they can be done in any wakaba, since I've only seen them in 4chan, but here's what I want to know.

1. How do I make a post as an admin/mod (like when a mod posts in 4chan, it shows the name in purple instead of green)?
2. How do I sticky posts?
3. And how do I add word filters?

Thanks in advance!
