I was wondering if there is a way to have a the search engines' names show up in the "Members Online Now" box instead of them showing up as guest? If this even happens on XF.
For what you're looking for, I don't think so.
However, you can view the IP of a visitor from the "who's online list" and find out if that visitor is a search engine crawler or not,
Hrm.. I'm kind of thinking about making this mod then. I just don't want to take the time making it and then it be released in the official software a month later?
