Downloaded and installed fine. Pretty straight forward to use. Does what it says on the tin.
Easy enough to use. No trouble installing. Excellent instructions on developers site which in the OS community is a pleasant surprise.
Only comment - Should have been a readme file with the name of tags to include as had to go to back to developers site to find out what they were.
Be very keen to see a version of this that can handle more than one experiment on a site.
