Question about an IE UA

[GaryK]

This isn't strictly about a search engine, but it is about a UA and we're all sort of UA experts here.

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 1.1.4322; .NET CLR 3.0.30618; .NET CLR 3.5.30729; yie8)

Anyone have a clue what the yie8 token means? I can't find anything definitive on Google about it. Thanks.

That was quick. Thanks so much, coop. :)
