Unsupported

This module adds settings allowing you to exclude specific types, severity levels and ip addresses from being logged to the database.
It does this by overriding the HOOK_watchdog function in the dblog module and implementing its own.
settings are with the other logging settings at: admin/config/development/logging

After implementing this module, I came across one that does virtually the same (though it doesn't seem to filter IP).

The Freebil Drupal 7 module is intended to serve as a mini billing system for small businesses or individuals. It was first conceived as an accounting tool for freelancers. It tracks customers, contacts, invoices, and payments. All customer, invoice and payment data is entered by the user via forms. An invoice is generated which can be emailed to the customer in text or HTML format. As payments are received, the user enters the payment data and the balance due is updated. A new invoice can be generated if there is still an outstanding balance.

This module is an enhancement for the learnline theme, which can be found here:

It offers some minor fixes, to fit the customer's demands. Use, extend, modify at your will, but also at your own risk.

This module is no longer useful because etrans (Área 54) no longer provides the service we use.

See Commerce Andreani or Commerce Urbano for other shipping solutions for Argentina.

This module will assign a role to an anonymous user if the HTTP_USER_AGENT is one of a specified set of values.

Use Cases

When the URL is pasted into the share textbox on Facebook, the page will be scraped for content and images. If the page is unpublished or protected, Facebook will cache an error page and this error page will be displayed for future shares. This condition persists unless manually rescraped.

Uses a web service via javascript to add cookies of the clients location.

A light weight alternative to other ip location modules with the downside of the location cookies not being available with the first page visit.

The actual cookies that are set depends on the web service that is selected on the admin page. The admin page allows you to test the service and see what cookies will be set.
Admin page: admin/config/people/location_cookie

A good use case is using the location cookie as a views contextual filter (this is what I use it for).
