Personally, if I come across a word or expression that I do not recognize in the forums, I Google the crap out of it. Well, provided I search through the rest of the thread and it isn't explained there already. I'm too impatient to post a reply asking what they mean and then wait for someone to notice and get back to me. How do you handle it? Do you do a search, ask in the thread or maybe just avoid posting altogether? Or something else entirely? Perhaps you've yet to come across something that you didn't understand - in which case you're welcome to reply with what you /think/ you would do.
