CL Simplest SMTP


I've been using Carlos's SMTP plugin for WordPress, and honestly, it's exactly what I needed. Super easy to set up, no complicated menus or unnecessary extras. Within minutes, I had it up and running, and it fixed all my email delivery issues like a charm.



The best part? It's lightweight and doesn't slow down the site, which is a big win. Plus, it works perfectly with providers like Gmail and Outlook—I haven’t had a single issue since installing it.



If you're looking for something simple, effective, and hassle-free, this is the plugin for you. Great job, Carlos!


Fantastic!


Great plugin for configure your own SMTP mail server. Simple, easy to install and works fine. And the best feature, you can define the data in variables in your wp-config.php. 



It's an excellent choice for me.


Excelent plugin to configure the SMTP server mail


Carlos nails it!!



We are pleased to have this simple plugin without the useless options that others add.Thank you!!

Library Management System (LMS) is a WordPress plugin that helps you run your library from the admin panel and on the frontend. Manage books, users, branches, bookcases, sections, and full borrow/return workflows with late fines and reporting. Whether you run a small community library or a school/college library, the free version gives you the core tools to operate efficiently.
<h3>Why Choose Library Management System?</h3>
📚 Complete Library Control — Organize your collection with categories, bookcases, and sections. Add books with details (name, ISBN, author, publication, cover image, stock) and manage your catalogue from one dashboard.
👥 User & Branch Management — Manage library branches and LMS users with contact details. Keep track of who borrowed what and from which branch.
📖 Borrow & Return — Process book checkout and returns with configurable loan periods. Track every transaction and return condition (normal, damaged, late). Calculate and manage late fines from the return list.
📊 Reports & Export — Generate detailed reports with filters and export to PDF, print, or CSV. See borrow history, return history, and key metrics at a glance.
🌐 Public Library Page — Display your book collection on the frontend with the [owt7_library_books] shortcode. Visitors can browse books; logged-in users get a single book page view. Pagination and filters keep the listing tidy.
⚙️ Flexible Settings — Configure borrow days, late fines, country, currency, and shortcode options. Multilingual support (English, Hindi, Italian, Spanish, French) and test data import help you get started quickly.
