I'm new to K2 and i wanna to make a blog with it.
I already have all my (blog) items on my home page but now i wanna have one item that stays on top of the first page of my blog. Is this possible ?

So this is what i want :

Welcome/intro item

---

Blog item from today

---

Blog item yesterday

---

Blog item last week

---

Nobody ? :(

That sorta doesnt go along with the ordering scheme of things. I would put the welcome item in a com_k2_content module and display it in a module position if your template allows, or build it into the category description of the category you are showing (if only one)
