There are quite a number of sites & blogs on Sri Vaishnavam. Here are a few which are worth visiting. Do take a moment and visit the sites and do not forget to leave your comments and suggestions to the site owners. Your comments & suggestions encourage the owners to develop the sites.
This site is the brain-child of Sri Murali Battar, a descendant of Sri Gopala Bhat Goswami Miras Archakar at Srirangam Temple. The site is regularly updated with news from the Sri Rangam temple. Photos of events in the temple are also regularly uploaded.
This site contains a really vast amount of information and is also regularly updated. Read more about the site in one of my blog posts. You can also listen to Upanyasams online in this site. A MUST VISIT site.
A regularly updated site created by Sri Vaishnavas in The United States. Free e-Books, e-Journals, Tele Upanyasams are available in the site. Dig through the various links and you are sure to find a lot of useful information. A re-design would help the visitors easily access all the contents.
This is the website of the famous publishing house Sri Vaishnava Sri. It contains information about the their publications, pictures and more. But the site is less regularly updated and tad poor on design & functionality.
This site has lots of information on works of Sri Ramanujar, Sri Manavala Mamuni, Sri Vedanta Desikar and more. The site contains details and summaries on works like Sri-Bhashya, Vedarthasangraha, Divya Prabandham and lots more. Information on Alwars, famous vaishnavite temples and many more are available. But this site has not been updated for a long time. Kindly e-mail the site owner to update the site more often.
The best thing about the above site is its collection of rare books in pdf format, which are free for download (http://www.srivaishnava.org/rare/).
As the name implies this is the site of the Kinchitkaram Trust of Sri Velukkudi Krishnan Swamy. The site is very engaging and shows a lot of promise. Some pages are still under construction. This site also has a blog. Definitely a MUST VISIT.
