I've got a question and a suggestion :
- Did you use phrases for this hack ? I was trying to find phrases using phrases search but didn't find any .If you didn't I hope you do with the next release ,this make life a bit more easy

- Also since the search engines spiders could be a large factor ,keeping a track of them will be unrealistic indication about the forum guests .maybe you can add an option to exclude them .
Other than that I can say nothing but thanks again for that hack .
