Well, it is nice to meet you and welcome to. Please be sure to read the list of site policies before making edits or constructing pages. :P

As for your question, no, admins are not limited to using that mechanism. It is easy to do but tends to annoy people (that is why I do it, mostly XD). Anywho, check out Template:Greeting and that should give you everything you need.
