  I found a couple of weird cookies that are apparently from WordPress.com and wondered if anyone can tell me what they are for? (Or should I ask support?)

  The cookies names are:

  optimizelyEndUserID

  and

  optimizelyBuckets

  The blog I need help with is: (visible only to logged in users)

  This is probably a question for staff. I’ll tag this thread for their attention as it would be nice to have the answer here in the forums.

  macmanx –
  Sorry for the delay, I was just about to answer your question when my computer crashed and was out of action for days, and then I just forgot!
