As suggested by Matt in his Thank a Plugin Developer Day post in WordPress.org, I took some time off the usual tasks and went to WP plugin and theme developers site and contact page and sent some thank you notes. I have not thanked all yet so I hope it can be a week for thank you’s and not just a day. Sorry guys, its just thank you notes for now, no money for paypal yet.
Again, my warmest thanks to all the developers of plugins and themes and all those stuffs in WP. This is really a great community and I am glad to be part of it.
