I'm selling very popular inventory lookup system - nwatch
It's a secure status php script for l2off that connects to mssql l2off server (soon for mysql java!) and display's player's info such as level, items, class, subclass info, dyes, skills etc etc.
It also displays some various clan info and their players.

You cannot get these files anywhere else.
I am the only one selling them.
If you are trying to buy them from someone else they are most likely scammers (or selling much older versions and provide no support/updates).
I provide support if needed (installation, bugfixes);
Installation upon request;
Customization (php/design) upon request;
"L2server-name" is changed to your server name on purchase.
Info on msn: 
Contact me for any questions, cost and purchase.
If you are uncertain either I am legit or not (It should be obvious by now I am NOT a scammer) pm me.
I have plenty of evidence to confirm I'm legit.
