Hi Bishnu,

the mailing list for the Rufus-Scheduler is at :

```
http://groups.google.com/group/rufus-ruby

```

To subscribe without a gmail account :

```

```

Anyway :

```
 "`require': no such file to load -- kk/rufus-scheduler-1.0.5 

```

(LoadError)"

seems to indicate that your logon.rb is trying to load  
“kk/rufus-scheduler-1.0.5” which probably doesn’t exist.

Best regards,
