Just curious, what does RELz/WIPz stand for? I think I understand REQ easy enough, but lost on the others...
Sorry for noob question.
As the above poster noted.
Also, back in the OLD days, you could search for 3 letter words, so we had REL and WIP. Then the policy changed to require at least 4 letters (For performance reasons on the server, they said) so the community stuck with the initial abbreviations and added a letter - which is why they both have a 'z' at the end.
