I like it very much and it worked thanks to this tip

if u are not using the scripted called "jquery-1.1.3.1.pack.js"
go to the tamplate called "mrnasesimilarthreadcheck_header", find the script name (is easy) and change that name to the one you have uploaded in your clientscript folder (it works ^^)

However I've uninstalled it because I've some reserved and private forum and I've noticed that this plugin search also (and show the results!!!) also on these forum.

It's not possible to avoid the search in some forum? I've tried to put the private forum ID in the settings but these settings are not meant to avoid the search.
