As a new member of this community, I am having a bit of difficulty with the numerous abbreviations that people use in their writing on this site. For example I have come across a number of these that are not listed on the Jargon page (eg: EY, PC, NPC, MWI...). I realize that as a new member, I will eventually understand many of these, however, it is very frustrating trying to read something and be continually distracted by having to look-up some of these obscure terms. This is especially a problem on the Welcome Thread, where a potential new member could be put off by the argot like discussions. Alternatively, if someone want to use an abbreviation that is not common or listed on the Jargon page, then perhaps they could spell it out at first use and then resort to the abbreviation thereafter within the post. Or set-up and use a text-expander is also another possible solution.
