I honor her along with all of the deities, but I don't "pray" to any of them. I consider it demeaning to both myself and the target deity or other spiritual entity. I don't personally know anyone who does pray to her, but I'll star your Q so if some of the other Folk come on later they'll be more likely to see it.
Rev, it can be spelled a couple of different ways, as most of the names in our pantheon can. Loke = Loki = Lokju = Lopti = well, you get the idea. It's all variants on the same dude's name, usually regional or dialectical or having to do with a specific aspect. It gets really fun when we start referring to them using kennings. Old One Eye - Odin. The Red One - Thor. The Sly One - Loki.
We like being shifty that way, ya know. ;-)
