Gah, I HATE that! I hate having to ask what something is - heck, sometimes I've even used the equip list as a shortcut to the MP, when I see an item I've been meaning to buy! xD
I always leave it on, and I'm happy to answer questions, especially since I tend to have four-line equipped lists and sometimes even I'll look at it and go "I know I have that evo on, but what pose is it again?" When I get stumped, I just screenshot and host it, then make a Q+A thread, asking. They've only failed me once, and I think the issue was it was an old item that looks much better on male avvies than female. :*(
