[LanX]: SUPER STABLE!!!
[marinersk]: LanX++ LOL Yes, that is another workaround. :-)
[LanX]: strangely you can't disable the XP nodelet
[LanX]: But you can use CSS to hide it
[LanX]: and disoplay the data permanently in your peronal nodelet
[marinersk]: I saw that you could post it on the Personal Nodelet, but you have to provide the content also. No way to auto-populate it. Not that this would solve my distraction problem...
[LanX]: there are template variables to "Auto-populate" it
[marinersk]: Yeah, someday I might become interested enough to poke around PerlMonks more internally. Most of the fancy stuff is way down on my to do list.
