Hello,

welcome to this ELOG demonstration. It contains a logbook for Linux Tips & 
Tricks. You can use the arrow buttons on the top right corner to browse 
this logbook, use the "Find" link to search for certain entries in the 
logbook and the "New" link to enter a new entry. The write access is not 
password protected so everybody can submit entries, since this is just a 
demonstration. Each submission causes an automatic email notification to 
the author.

When submitting entries, attachments can be added just like with email 
programs. This entry for example contains a JPG attachment and a text 
attachment.
